videobuf2 has long been subject to AB-BA style deadlocks due to the queue lock and mmap_sem being taken in different orders for the mmap operation. The problem has been fixed by making this operation callable without taking the queue lock, using an mmap_lock internal to videobuf2. The omap3isp driver still calls the mmap operation with the queue lock held, resulting in a potential deadlock. As the operation can now be called without locking the queue, fix it. Signed-off-by:

The release_firmware() function was called in three cases by the mn88472_init() function during error handling even if the passed variable "fw" contained still a null pointer. This implementation detail could be improved by the introduction of another jump label. Signed-off-by:

The release_firmware() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by:

The video and pad ops are duplicates, so get rid of the more limited video op. The whole point of the subdev API is to allow reuse of subdev drivers by bridge drivers. Having duplicate ops makes that much harder. We should never have allowed duplicate ops in the first place. A lesson for the future. Signed-off-by:

Support the new 'which' field in the enum_frame_interval ops. Most drivers do not need to be changed since they always returns the same enumeration regardless of the 'which' field. Tested for ov7670 and marvell-ccic on a OLPC XO-1 laptop. Signed-off-by:

While all other pad ops allow you to select whether to use the 'try' or the 'active' formats, the enum ops didn't have that option and always used 'try'. However, this will fail if a simple (e.g. PCI) bridge driver wants to use the enum pad op of a subdev that's also used in a complex platform driver like the omap3. Such a bridge driver generally wants to enum formats based on the active format. So add a new 'which' field to these structs. Note that V4L2_SUBDEV_FORMAT_TRY is 0, so the default remains TRY (applications need to set reserved to 0). Signed-off-by:

If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL. Signed-off-by:

Since 39b2bbe3 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Simplify accordingly. Moreover use devm_gpiod_get_index_optional instead of devm_gpiod_get_index with ignoring all errors. Signed-off-by:

the declaration for omap_vout_setup_vrfb_bufs() said it needed 'u32 static_vrfb_allocation' but definition took 'bool static_vrfb_allocation', this patch fixes the declaration so that it matches with the definition and pass a bool instead of int to the call, also included omap_vout_vrfb.h in omap_vout_vrfb.c file so that sparse doesn't complain of making omap_vout_setup_vrfb_bufs() as static function.

Embed video_device structs vdev and vbi_dev in au0828_dev. With this change, dynamic allocation and error path logic in au0828_analog_register() is removed as it doesn't need to allocate and handle allocation errors. Unregister path doesn't need to free the now static video_device structures, hence, changed video_device.release in au0828_video_template to point to video_device_release_empty. Signed-off-by:

The vbi_buffer_filled() and buffer_filled() did the same functionality except for incrementing the buffer sequence, this patch drops the vbi_buffer_filled() and re-uses buffer_filled() for vbi buffers as well by adding the check for vb2-queue type while incrementing the sequence numbers. Along side this patch aligns the input parameters of buffer_filled() function appropriately. Signed-off-by:

Use pr_foo() where there's a direct replacement. For debug, use custom-made macros, for now, as there are 3 different debug levels. We should get rid of those some day, specially since several such macros can be just removed, as Kernel trace would provide about the same output.
