Use proper return value test for clk_get() and devm_regulator_get() functions and propagate any errors from the clock and the regulator subsystem to the driver core. In two cases a proper error code is now returned rather than 0. Reported-by:

This patch patch eliminates potential AB-BA deadlock when one process calls open(), or VIDIOC_S/TRY_FMT ioctl on the FIMC capture video node, while other thread is reconfiguring media links via media device node: /dev/video? open() /dev/media? MEDIA_IOC_SETUP_LINK ioctl mutex_lock(video_lock) mutex_lock(graph_lock) fimc_pipeline_open() fimc_md_link_notify() mutex_lock(graph_lock) mutex_lock(video_lock) ... ... The deadlock is avoided by always taking the graph mutex first in video node open() or an ioctl, before the video lock is acquired. Reversed order seems impossible, since media device driver's link_notify callback is called with media graph mutex already held. To ensure proper locking order VIDIOC_S_FMT and VIDIOC_TRY_FMT ioctls are not serialized in the v4l2-core and the driver takes care of it itself. Signed-off-by: -

This fixes following issue found with a static analysis tool: Pointer 'ffmt' returned from call to function 'fimc_capture_try_format' at line 1522 may be NULL and may be dereferenced at line 1535. Although it shouldn't happen in practice, add the NULL pointer check to be on the safe side. Signed-off-by:

There is no need to keep dummy sleep() callback implementation as DVB-core checks existence of it before calls callback. Due to that we can remove it. FC0012 is based of direct-conversion receiver architecture (aka Zero-IF) where is no IF used. Due to that IF is always 0 Hz. Fix comment to point that. Signed-off-by:

We need feed clock to slave demodulator at the very beginning in case of dual tuner configuration. I am not sure if that configuration changes clock output divider or enable clock output itself... Signed-off-by:

The above commit were applied only partially; it broke tuner and demod attach, but the part that added it to ngene_info was missing. Not sure what happened there, but, without this patch, a regression would be happening. Also, gcc complains about a defined but not used symbol. So, apply manually the missing part.

struct soc_camera_link currently contains fields, used both by sensor and bridge drivers. To make subdevice driver re-use simpler, split it into a host and a subdevice parts. Signed-off-by:

Guennadi Liakhovetski authored
Currently soc-camera has a per-device node lock, used for video operations and a per-host lock for code paths, modifying host's pipeline. Manipulating the two locks increases complexity and doesn't bring any advantages. This patch removes the per-device lock and uses the per-host lock for all operations. Signed-off-by:
-
Guennadi Liakhovetski authored
Currently devm_regulator_bulk_get() is called by soc-camera during host driver probing, but regulators are attached to the camera platform device, that is staying, independent whether the host probed successfully or not. This can lead to repeated regulator requesting, if the host driver is re-probed. Move the call to platform device probing to avoid this. Signed-off-by:

Guennadi Liakhovetski authored
The recently introduced host_lock causes lockdep warnings, besides, list enumeration in scan_add_host() must be protected by holdint the list_lock. OTOH, holding .video_lock in soc_camera_open() isn't enough to protect the host during its building of the pipeline, because .video_lock is per soc-camera device. If, e.g. more than one sensor can be attached to a host and the user tries to open both device nodes simultaneously, host's .add() method can be called simultaneously for both sensors. Fix these problems by holding list_lock instead of .host_lock in scan_add_host() and taking it shortly at the beginning of soc_camera_open(), and using .host_lock to protect host's .add() and .remove() operations only.
