2014-11-03[media] cx88: remove fmt from the buffer structHans Verkuil
This is a duplicate of dev->fmt and can be removed. As a consequence a lot of tests that check if the format has changed midstream can be removed as well: the format cannot change midstream, so this is a bogus check.

2014-10-30[media] af9005: fix kernel panic on init if compiled without IRFrank Schaefer
This patches fixes an ancient bug in the dvb_usb_af9005 driver, which has been reported at least in the following threads: https://lkml.org/lkml/2009/2/4/350 https://lkml.org/lkml/2014/9/18/558 If the driver is compiled in without any IR support (neither DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in af9005_usb_module_init() return pointers != NULL although the IR symbols are not available.

Until anyone who still has this old hardware steps up an does the conversion, fix it by not calling the symbol_request calls if the driver is compiled in without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE). Due to the IR related pointers beeing NULL by default, IR support will then be disabled. The downside of this solution is, that it will no longer be possible to compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in. Please note that this patch has NOT been tested with all possible cases. I don't have the hardware and could only verify that it fixes the reported bug.

The core problem was that the conversion from user to kernelspace was done at too low a level and that needed to be moved up. That made it possible to drop pointers to v4l2_ext_control from set_ctrl and validate_new and clean up this sparse warning because those functions now always operate on kernelspace pointers.

2014-10-28[media] s5p-mfc: fix a race in interrupt flags handlingPawel Osciak
Interrupt result flags have to be cleared before a hardware job is run. Otherwise, if they are cleared asynchronously, we may end up clearing them after the interrupt for which we wanted to wait has already arrived, thus overwriting the job results that we intended to wait for. To prevent this, clear the flags only under hw_lock and before running a hardware job.
