Tobias Lorenz 03dea86de2 V4L/DVB (7401): radio-si470x: unplugging fixed
This patch fixes several kernel oops, when unplugging device while it is in
use:

Basically the patch delays freeing of the internal variables in
si470x_usb_driver_disconnect, until the the last user closed the device in
si470x_fops_release. This was implemented a while ago with the help of Oliver
Neukum.

I tested the patch five times (unplugging while in use) without oops coming
from the radio-si470x driver anymore. A remaining oops was coming from the
usbaudio driver, but this is someone else task. Hopefully this fixed all
unplugging issues.

Mauro Carvalho Chehab b2cb200f0d V4L/DVB (7377): radio-sf16fmr2.c: fix volume handling
As reported by  Roel Kluin <12o3l@tiscali.nl>:

	        radio_qctrl[i].step = 65535;

I don't understand this '&& V4L2_CID_AUDIO_VOLUME'

Tobias Lorenz 5caf51342c V4L/DVB (7188): radio-si470x version 1.0.6
This patch combines all the finished discussions and its resulting patches from
the mailing list.

The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of
small issues, that are fixed with this patch now. For me the most interesting
thing is, that it's now safer to use it on other architectures.

The history for version 1.0.6 is:
- fixed coverity checker warnings in *_usb_driver_disconnect
- probe()/open() race by correct ordering in probe()
- DMA coherency rules by separate allocation of all buffers
- use of endianness macros
- abuse of spinlock, replaced by mutex
- racy handling of timer in disconnect, replaced by delayed_work
- racy interruptible_sleep_on(), replaced with wait_event_interruptible()
- handle signals in read()

The driver is tested with all Debian/testing radio programs and rdsd. The patch
is tested against checkpatch.pl v1.12.

Tobias Lorenz 0e3301ec23 V4L/DVB (7091): radio-si470x improvements and seldom problem fixed in tuning functions
I updated the radio-si470x driver another time. Here are the commented history entries:

- number of seek_retries changed to tune_timeout
The last versions checked for the end of frequency tuning by polling a si470x register.
Therefore polling depended on the usb utilization.
This was changed to have a constant timeout now.

- fixed problem with incomplete tune operations by own buffers
The last version used a shared buffer to assembly the USB HID reports.
It sometimes happened, that multiple functions were modifing this buffer simultanuously.
When sending such reports, the hardware returned USB stalls (-EPIPE).
Now buffers of the correct size (smaller than before) are allocated as local variables.

- optimization of variables
The size of some variables has been reduced to allow the compiler to generate more optimized code.

- improved error logging
At some important location, error checking was improved.
Especially the usb transfers to access si470x registers and the tuning functions were modified.

Mauro Carvalho Chehab 057596eea8 V4L/DVB (7133): Fix Kconfig dependencies
As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.

This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.

After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.

This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

Tobias Lorenz 78656acdcf V4L/DVB (7038): USB radio driver for Silicon Labs Si470x FM Radio Receivers
this patch adds a new driver for the Silicon Labs Si470x FM Radio Receiver. It
should also work for the identical ADS/Tech FM Radio Receiver (formerly
Instant FM Music) as soon as I find out the USB Vendor and Product ID.

The driver is inspired by several other USB and radio drivers, but mainly from
the D-Link DSB-R100 USB radio (dsbr100.c).

The USB stick currently has an Si4701 FM RDS radio receiver. But the other
Si470x devices are pin and register compatible, so that in the future the
driver can easily be patched to support these too. Therefore I named the
driver radio-si470x and the configuration option usb-si470x.

The driver itself just provides the control function over the radio. For
getting audio back, the device support the USB audio class, which is
implemented in the already existing driver.

I tested the driver in the last days, until it now satisfies all my
functionality and robustness requirements. The application I used for testing
was kradio.

Julia Lawall f37fdf3ff7 V4L/DVB (7036): radio: Use video_device_release rather than kfree
The file drivers/media/video/videodev.c defines both video_device_alloc and
video_device_release.  These are essentially just kzmalloc and kfree,
respectively, but it seems better to use video_device_release, as done in
the other media files, rather than kfree, in case the implementation some
day changes.

The problem was found using the following semantic match.

Auke Kok 44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

Trent Piepho 59faba1b31 Fix Kconfig dependency problems wrt boolean menuconfigs
If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result.  If BAZ=m, then BAR can be set
y, which allows FOO=y.  It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ.  In effect, the bool
promotes the tristate from m to y.

This ends up causing a problem with several menuconfigs that look like:

menuconfig BAR
	bool
	depends on BAZ [tristate]
if BAR
config FOO
	tristate
endif

The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ.  This is how it would work if a menu
was used instead of an if block.

Tim Schmielau cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Hans J. Koch c0c7fa0966 V4L/DVB (4406): Convert radio-cadet to V4L2 API
This is a card with RDS capabilities. 
RDS specifications didn't change from V4L1 to V4L2, so that part should be OK. 
This patch changed the following stuff:
* The device can be opened multiple times. That's necessary because there are 
at least a radio application and an RDS application (rdsd) that want to 
open() the device.
* Added a poll() function. Every character device should have that, and rdsd 
expects it as it uses select() on that file descriptor.
* Converted the ioctls to V4L2. MUTE is not implemented correctly as the 
card doesn't seem to have a special bit for that. Probably there are a few 
more ioctls that should at least return 0 or an error.
As I do not own such a card, I couldn't test anything. If there is anybody out 
there who owns such an ancient card, please test and report. 
I just checked that the code compiles.
