mem->dma_handle is a dma address obtained by dma_alloc_coherent which needn't be a physical address in presence of IOMMU, as a hardware IOMMU can (and most likely) will return a bus address where physical != bus address. So ensure we are remapping (remap_pfn_range) the right page in __videobuf_mmap_mapper by using virt_to_phys(mem->vaddr) and not mem->dma_handle. While at it, use PFN_DOWN instead of explicit shift.

The scheme used to index format in uvc_fixup_video_ctrl() is not robust: format index is based on descriptor ordering, which does not necessarily match bFormatIndex ordering. Searching for first matching format will prevent uvc_fixup_video_ctrl() from using the wrong format/frame to make adjustments. Signed-off-by:

Patch from Ian Armstrong. I've encountered a couple of problems with the current af9015 driver as supplied with the 2.6.37 kernel, that the attached patch appears to fix. (I've generated this patch against the current v4l-dvb git). Some key-presses are lost. A key-press is only generated upon 'valid' data (buf[14] == (u8) ~buf[15]), but the buffer is wiped before this check. Sometimes the 15th byte has not been set at the time of read, so the data isn't valid & ignored. On the next poll the 15th byte has been set, but the rest of the data was wiped previously, so the data is still invalid & the key is lost. Weird repeat error, where an old key press is sometimes repeated in error. ie. button sequence '1 (pause) 2 (pause) 3 (pause) 4' generates output like '1 (pause) 2 (pause) 23 (pause) 4'. The current driver zeroes the data for the key pushed, but sometimes this data is already zero but with other bytes set suggesting a repeat code. This results in the last key being incorrectly repeated. This patch attempts to reduce the risk of a missed key-press & also stop the random repeat of an old key-press when a new key is pressed.

Use pr_debug instead of printk so it is possible to control debug traces at runtime. E.g. to enable debug trace in file fimc-core.c use command: echo -n 'file fimc-core.c +p' > /sys/kernel/debug/dynamic_debug/control or echo -n 'file fimc-core.c -p' > /sys/kernel/debug/dynamic_debug/control to disable.
