media: omap3isp: fix unbalanced dma_iommu_mapping

[ Upstream commit b7e1e6859fbf60519fd82d7120cee106a6019512 ] The OMAP3 ISP driver manages its MMU mappings through the IOMMU-aware ARM DMA backend. The current code creates a dma_iommu_mapping and attaches this to the ISP device, but never detaches the mapping in either the probe failure paths or the driver remove path resulting in an unbalanced mapping refcount and a memory leak. Fix this properly.

media: rc: mce_kbd decoder: low timeout values cause double keydowns

2018-08-03T05:48:00+00:00

[ Upstream commit c421c62a4a08aba220ad7176ef4aa4b0ced9480a ] The mce keyboard repeats pressed keys every 100ms. If the IR timeout is set to less than that, we send key up events before the repeat arrives, so we have key up/key down for each IR repeat. The keyboard ends any sequence with a 0 scancode, in which case all keys are cleared so there is no need to run the timeout timer: it only exists for the case that the final 0 was not received.

media: renesas-ceu: Set mbus_fmt on subdev operations

2018-08-03T05:47:53+00:00

[ Upstream commit d3a67f27471d4792caf84132228def2b18617932 ] The renesas-ceu driver intializes the desired mbus_format at 'complete' time, inspecting the supported subdevice ones, and tuning some parameters to produce the requested memory format from what the sensor can produce. Although, the initially selected mbus_format was not provided to the subdevice during set_fmt and try_fmt operations, providing instead a '0' mbus format code. As long as the sensor defaults to a compatible mbus_format when an invalid code as '0' is provided, capture operations work correctly. If the subdevice defaults to an unsupported format (eg. some RGB permutations) capture does not work properly due to a mismatch on the expected and received image format on the wire. Fix that by re-using the initially selected mbus_format code during set_fmt and try_fmt subdevice operation calls. Tested by printing out the format selection procedure with ov7670 sensor.

media: saa7164: Fix driver name in debug output

[ Upstream commit 0cc4655cb57af0b7e105d075c4f83f8046efafe7 ] This issue was reported by a user who downloaded a corrupt saa7164 firmware, then went looking for a valid xc5000 firmware to fix the error displayed...but the device in question has no xc5000, thus after much effort, the wild goose chase eventually led to a support call. The xc5000 has nothing to do with saa7164 (as far as I can tell), so replace the string with saa7164 as well as give a meaningful hint on the firmware mismatch.
