3e645d6b48 v4l1: fix 32-bit compat microcode loading translation
The compat code for the VIDIOCSMICROCODE ioctl is totally buggered.
It's only used by the VIDEO_STRADIS driver, and that one is scheduled to
staging and eventually removed unless somebody steps up to maintain it
(at which point it should use request_firmware() rather than some magic
ioctl).  So we'll get rid of it eventually.

But in the meantime, the compatibility ioctl code is broken, and this
tries to get it to at least limp along (even if Mauro suggested just
deleting it entirely, which may be the right thing to do - I don't think
the compatibility translation code has ever worked unless you were very
lucky).

b2b476f53a V4L/DVB: v4l: videobuf: prevent passing a NULL to dma_free_coherent()
When a driver that uses videobuf-dma-contig is used with the USERPTR
memory access method a kernel oops might happen: a NULL address may be
passed to dma_free_coherent(). This happens when an application calls
REQBUFS and then exits without queuing any buffers. This patch fixes
that bug.

a08c7c68f7 V4L/DVB: ir-core: Fix null dereferences in the protocols sysfs interface
For some cards, ir_dev->props and ir_dev->raw are both NULL. These cards are
using built-in IR decoding instead of raw, and can't easily be made to switch
protocols.

So upon reading /sys/class/rc/rc?/protocols on such a card, return 'builtin' as
the supported and enabled protocol. Return -EINVAL on any attempts to change
the protocol. And most important of all, don't crash.

2fc11536cf V4L/DVB: videobuf-dma-sg: set correct size in last sg element
This fixes a nasty memory corruption bug when using userptr I/O.
The function videobuf_pages_to_sg() sets up the scatter-gather list for the
DMA transfer to the userspace pages. The first transfer is setup correctly
(the size is set to PAGE_SIZE - offset), but all other transfers have size
PAGE_SIZE. This is wrong for the last transfer which may be less than PAGE_SIZE.

Most, if not all, drivers will program the boards DMA engine correctly, i.e.
even though the size in the last sg element is wrong, they will do their
own size calculations and make sure the right amount is DMA-ed, and so seemingly
prevent memory corruption.

However, behind the scenes the dynamic DMA mapping support (in lib/swiotlb.c)
may create bounce buffers if the memory pages are not in DMA-able memory.
This happens for example on a 64-bit linux with a board that only supports
32-bit DMA.

These bounce buffers DO use the information in the sg list to determine the
size. So while the DMA engine transfers the correct amount of data, when the
data is 'bounced' back too much is copied, causing buffer overwrites.

The fix is simple: calculate and set the correct size for the last sg list
element.

The logic in ir_timer_keyup was inverted.

In case that values aren't equal,
the meaning of the time_is_after_eq_jiffies(ir->keyup_jiffies) is that
ir->keyup_jiffies is after the the jiffies or equally that
that jiffies are before the the ir->keyup_jiffies which is
exactly the situation we want to avoid (that the timeout is in the future)

[ 1351.281284] ir_keyup: keyup key 0x0067

ie one key down event and one key up event 250ms later.

So, we need to increase the repeat timeout, to avoid this bug to hit.

As we're doing it at core, this fix is not needed anymore at dib0700 driver.

Conexant cx231xx + Fujitsu 86A20S demodulator. However, both shares

We know for sure that bcd 0x100 is used for a dib0700 device, while
bcd 0x4001 is used for a cx23102 device. This patch reserves two ranges,
the first one from 0x0000-0x3f00 for dib0700, and the second from
0x4000-0x4fff for cx231xx devices.

This may need fixes in the future, as we get access to other devices.

There is only one caller for this function and it passes non-NULL

Those breakages seem to be caused by two bad things at IR_CORE Kconfig:

1) cx23885 is using select for IR_CORE;
2) the dvb-usb and sms dependency for IR_CORE were missing.

While here, allow users to un-select IR.

Now that i2c-core offers the possibility to provide custom probing
function for I2C devices, let's make use of it.

The probe method used by i2c_new_probed_device() may not be suitable
for all cases. Let the caller provide its own, optional probe
function.

560afa7d85 V4L/DVB: tvp7002: fix write to H-PLL Feedback Divider LSB register
H-PLL Feedback Divider LSB register is an 8 bit register out
of which the first 4 bits are reserved. Current code is
writing to these reserved location. This patch corrects
this issue by left shifting the values being written to the
register by 4.

This patch has been tested on DM6467 EVM with 720P-60 and
1080I-60 inputs.

d0a38ce27e V4L/DVB: dvb: siano: free spinlock before schedule()
Calling schedule() holding spinlock with disables irqs is improper. As
spinlock protects list coredev->buffers, it can be unlocked untill wakeup.
This bug was introduced in a9349315f6.
