If, in usb_hid_configure(), we fail to allocate storage for 'usbhid',
"if (!(usbhid = kzalloc(sizeof(struct usbhid_device), GFP_KERNEL)))",
then we'll jump to the 'fail:' label where we have this code:
usb_free_urb(usbhid->urbin);
usb_free_urb(usbhid->urbout);
usb_free_urb(usbhid->urbctrl);
Since we got here because we couldn't allocate storage for 'usbhid',
what we have here is a NULL pointer dereference - ouch...
This patch solves that little problem by adding a new
'fail_no_usbhid:' label after the problematic calls to
usb_free_urb() and jumps to that one instead, in the problem case.

This updates some error reporting paths in SPI device setup:
- Move validation logic for SPI chipselects to spi_new_device(),
which is where it should always have been.
- In spi_new_device(), emit error messages if the device can't
be created. This is LOTS better than a silent failure; though
eventually, the calling convention should probably change to
use the <linux/err.h> conventions.
- Includes one previously-missing check: SPI masters must always
have at least one chipselect, even for dedicated busses which
always keep it selected!
It also adds a FIXME (IDR for dynamic ID allocation) so the issue doesn't live
purely in my mailbox.

This is only called at init time and only happens if the BIOS screws
something up, so the leak is slight and it is probably not worth sending to
2.6.22.x. The driver would not initialize the interface in the case, and I
have no reports of this happening. I have booted and run tests on a system
with this patch. Note that the original patch was munged by the mailer,
here's a new one.
If we ever hit the "default:" case in the switch in try_init_dmi(),
then we'll leak the storage allocated with kzalloc() and assigned
to 'info'.

doesn't wait for the abort to complete before restarting it which creates a

Instead, do the abort when the SDMA engine is being stopped. Make sure to
