In case of error, the function devm_clk_get() returns ERR_PTR() and not returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

When transmitting a message and waiting for a reply it would be good to know the time between when the message was transmitted and when the reply arrived. With only one timestamp field it was set to when the reply arrived and the original transmit time was overwritten. Just taking the timestamp in userspace right before CEC_TRANSMIT is called is not reliable, since the actual transmit can be delayed if the CEC bus is busy. Only the driver can fill this in accurately. So split up the ts field into an rx_ts and a tx_ts. Also move the status fields to after the 'reply' field: they were placed in a strange position and make much more sense when grouped with the other status-related fields. This patch also makes sure that the timestamp is taken as soon as possible. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

The DW2102 DVB-S/S2 driver uses the info() logging function from dvb-usb.h. This function already appends a newline to the provided log message, causing the dmesg output from DW2102 to include blank lines. Fix this by removing the newline in the calls to info().

Fix a number of bugs that appeared when support for mediabus formats was added: - Support for V4L2_DV_RGB_RANGE_FULL/LIMITED should only be enabled for HDMI RGB formats, not for YCbCr formats. Since, as the name says, this setting is for RGB only. So read the InfoFrame to check the format. - the quantization range for the pixelport depends on whether the mediabus code is RGB or not: if it is RGB, then produce full range RGB values, otherwise produce limited range YCbCr values. This means that the op_656_range and alt_data_sat fields of the platform data are no longer used and these will be removed in a following patch. - when setting up a new format the RGB quantization range settings were never updated. Do so, since this depends on the format. - fix the log_status output which was confusing and incorrect.

Commit 1fb69bfd (adv7511: improve colorspace handling) introduced a number of bugs, specifically with regards to YCbCr output and quantization range handling: - if the output is not RGB, then disable the full-to-limited range CSC matrix since that is meant for RGB formats. YCbCr formats are always limited range, so there is nothing to convert. (OK, full range YCbCr is possible, but we don't support that right now). - the mediabus code that was passed to adv7511_set_fmt was always cleared by the memset in adv7511_fill_format. This made it effectively impossible to select YCbCr output. - adv7511_set_fmt never updated the rgb quantization range.

When disconnecting the usbtv device, the sound card is unregistered from ALSA and the snd member of the usbtv struct is set to NULL. If the usbtv snd_trigger work is running, this can cause a race condition where the kernel will attempt to access free'd resources, shown in [1]. This patch fixes the disconnection code by cancelling any snd_trigger work before unregistering the sound card from ALSA and checking that the snd member still exists in the work function.
