The device information structure is currently copied field by field in the uvc_device structure. As we only have two fields at the moment this isn't much of an issue, but it prevents easy addition of new info fields. Fix this by storing the uvc_device_info pointer in the uvc_device structure. As a result the uvc_device meta_format field can be removed. The quirks field, however, needs to stay as it can be modified through a module parameter. As not all device have an information structure, we declare a global "NULL" info instance that is used as a fallback when the driver_info is empty. Signed-off-by:

The use of ALIGN() in uvc_alloc_entity() is incorrect, since the size of (entity->pads) is not a power of two. As a stop-gap, until a better solution is adapted, use roundup() instead. Found by a static assertion. Compile-tested only. Fixes: 4ffc2d89 ("uvcvideo: Register subdevices for each entity") Signed-off-by:

Fix error handling of v4l2_ctrl creation by inspecting the ctrl.error flag instead of testing for each returned value correctness. As reported by Dan Carpenter returning PTR_ERR() on the v4l2_ctrl_new_std() return value is also wrong, as that function return NULL on error. While at there re-order the cleanup path to respect the operation inverse order. Fixes: aab7ed1c "media: i2c: Add driver for Aptina MT9V111" Reported-by:

A new helper function was introduced to facilitate the calculation of time per frame value whenever we have access to the full v4l2_dv_timings structure. This should be used only for receivers and only when there is enough accuracy in the measured pixel clock value as well as in the horizontal/vertical values. Signed-off-by:

Add a new flag to UAPI for DV timings which, whenever set, indicates that hardware can detect the difference between regular FPS and 1000/1001 FPS. This is specific to HDMI receivers. Also, it is only valid when V4L2_DV_FL_CAN_REDUCE_FPS is set. Signed-off-by:

pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This should not be considered an error. Generally the driver has enabled runtime PM already so getting this error due to runtime PM being disabled will not happen. Instead of checking for lesser or equal to zero, check for zero only. Address this for drivers where this pattern exists. This patch has been produced using the following command: $ git grep -l pm_runtime_get_if_in_use -- drivers/media/i2c/ | \ xargs perl -i -pe 's/(pm_runtime_get_if_in_use\(.*\)) \<\= 0/!$1/' Signed-off-by:

Replace the calls to pm_runtime_get_noresume() and pm_runtime_put() with pm_runtime_idle() in the driver's probe function. This will have the same effect with fewer calls. pm_runtime_disable() in remove is sufficient as the device is already in RPM_SUSPENDED state. Signed-off-by:

Add support for 4:2:2, 4:4:4 and RGB 24/32 bits formats. This makes it a lot more useful, esp. as a simple video compression codec for use with v4l2-ctl/qvidcap. Note that it does not do any conversion between e.g. 4:2:2 and 4:2:0 or RGB and YUV: it still just compresses planes be they Y/U/V or R/G/B. Signed-off-by:
