Move firmware allocation from open to probe to avoid problems when using CMA for allocation. In certain circumstances CMA may allocate buffer that is not in the beginning of the MFC memory area. Signed-off-by:

Checking unsigned variable for negative value always returns false. Hence make this value signed as we expect it to be negative too. Fixes the following smatch warning: drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c:572 s5p_mfc_set_enc_ref_buffer_v6() warn: unsigned 'buf_size1' is never less than zero. Signed-off-by:

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.
