It was completely unnecessary to use BUG in saa7164_s_frequency, just return an error instead. This also solves a smatch error: drivers/media/pci/saa7164/saa7164-encoder.c:388 saa7164_s_frequency() error: potentially dereferencing uninitialized 'tsport'. Signed-off-by: -

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not make any sense. This also fixes this !CONFIG_OF error: drivers/staging/media/sunxi/sun6i-isp/sun6i_isp.c:529:34: warning: 'sun6i_isp_of_match' defined but not used [-Wunused-const-variable=] 529 | static const struct of_device_id sun6i_isp_of_match[] = { | ^~~~~~~~~~~~~~~~~ Signed-off-by:Chen-Yu Tsai <wens@csie.org>

The kernel already has a helper to print a hexdump of a small buffer via pointer extension. Use that instead of open coded variant. In long term it helps to kill pr_cont() or at least narrow down its use. Signed-off-by:

The flag FBINFO_FLAG_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by kzalloc(). So do not set it. Flags should signal differences from the default values.

CAL uses get_frame_desc to get the VC and DT for the incoming CSI-2 stream, but does it in a bit hacky way. Clean this up by implementing .get_frame_desc to camera-rx, and calling that from cal.c. No functional change intended. Signed-off-by:

Clean up the CAL drivers uses of mbus formats: - Switch all YUV formats from 2X8 formats to 1X16, as those are what should be used for CSI-2 bus. - Drop 24 and 32 bit formats, as the driver doesn't support them (see cal_ctx_pix_proc_config()). - Switch RGB565_2X8_LE to RGB565_1X16 (for the same reason as for the YUV formats) and drop RGB565_2X8_BE as it cannot be supported with CSI-2.

The imx8mq-mipi-csi2 MIPI CSI-2 receiver driver is used and maintained. There is no reason to keep it in staging. The accompanying CSI bridge driver that uses it is in drivers/media/platform/nxp as well. One TODO is to get rid of csi_state's "state" and "lock" variables. Especially make sure suspend/resume is working without them. That can very well be worked on from the new location. Also add a MAINTAINERS section for the imx8mq-mipi-csi2 mipi receiver driver.

When capturing 1600x900, system could crash when system memory usage is tight. The way to reproduce this issue: 1. Use 1600x900 to display on host 2. Mount ISO through 'Virtual media' on OpenBMC's web 3. Run script as below on host to do sha continuously #!/bin/bash while [ [1] ]; do find /media -type f -printf '"%h/%f"\n' | xargs sha256sum done 4. Open KVM on OpenBMC's web The size of macro block captured is 8x8. Therefore, we should make sure the height of src-buf is 8 aligned to fix this issue. Signed-off-by:

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes. Signed-off-by:

In gl861_i2c_master_xfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach gl861_i2c_master_xfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.
