Now that rc_register_device() is reorganised, the dev->initialized hack can be removed. Any driver which calls rc_register_device() must be prepared for the device to go live immediately. The dev->initialized commits that are relevant are commit c73bbaa4 ("[media] rc-core: don't lock device at rc_register_device()") and commit 08aeb7c9 ("[media] rc: add locking to fix register/show race"). The original problem was that show_protocols() would access dev->rc_map.* and various other bits which are now properly initialized before device_add() is called. At the same time, remove the bogus "device is being removed" check. Signed-off-by:

The device core infrastructure is based on the presumption that once a driver calls device_add(), it must be ready to accept userspace interaction. This requires splitting rc_setup_rx_device() into two functions and reorganizing rc_register_device() so that as much work as possible is performed before calling device_add(). Signed-off-by:

This patch add cec driver for STM32 platforms. cec hardware block isn't not always used with hdmi so cec notifier is not implemented. That will be done later when STM32 DSI driver will be available. Driver compliance has been tested with cec-ctl and cec-compliance tools. Signed-off-by:

Return NULL, if a null entity is parsed for it's v4l2_subdev Currently, the callers of media_entity_to_v4l2_subdev() need to make sure that the subdev is non-NULL, for example, when it is obtained from media_entity_remote_pad(). As this is a recurring pattern, add the check at the macro in order to avoid additional checks at the callers. Signed-off-by:

The buffer cache should be synchronised in buffer preparation, not when the buffer is queued to the device. Fix this. Mmap buffers do not need cache synchronisation since they are always coherent. Signed-off-by:

hmm_init calls hmm_alloc to set dummy_ptr, hmm_alloc calls hmm_init when dummy_ptr is not yet set, which is the case in the call from hmm_init, so it calls hmm_init again, this continues until we have a stack overflow due to the recursion. This commit fixes this by adding a separate flag for tracking if hmm_init has been called. Not pretty, but it gets the job done, eventually we should be able to remove the hmm_init call from hmm_alloc. Signed-off-by:

As the existing comment in the driver indicates the sensor has only 1 pin, but some boards may have 2 gpios defined and we toggle both as we we don't know which one is the right one. However if the ACPI resources table defines only 1 gpio (as expected) the gpio1_ctrl call will always fail, causing the probing of the driver to file. This commit ignore the return value of the gpio1_ctrl call, fixing this. Signed-off-by:

Do not call dev_warn with a NULL device, this silence the following 2 warnings: [ 14.392194] (NULL device *): Failed to find gmin variable gmin_V2P8GPIO [ 14.392257] (NULL device *): Failed to find gmin variable gmin_V1P8GPIO We could switch to using pr_warn for dev == NULL instead, but as comments in the source indicate, the check for these 2 special gmin variables with a NULL device is a workaround for 2 specific evaluation boards, so completely silencing the missing warning for these actually is a good thing.

efivar_entry_get has certain alignment requirements and the atomisp platform code was not honoring these, causing an oops by triggering the WARN_ON in arch/x86/platform/efi/efi_64.c: virt_to_phys_or_null_size(). This commit fixes this by using the members of the efivar struct embedded in the efivar_entry struct we kzalloc as arguments to efivar_entry_get(), which is how all the other callers of efivar_entry_get() do this.

The isp->inputs[] array has isp->input_cnt elements which have been initialized so this > should be >=. This bug is harmless. The check against ATOM_ISP_MAX_INPUTS prevents us from reading beyond the end of the array. The uninitialized elements are zeroed out so we will end up returning -EINVAL a few lines later because the .camera pointer is NULL. Signed-off-by:
