In af9035_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 af9035_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. Similar commit: commit 0ed554fd ("media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()") Signed-off-by:

The previous commit 4b208f8b ("[media] siano: register media controller earlier")moves siano_media_device_register before smscore_register_device, and adds corresponding error handling code if smscore_register_device fails. However, it misses the following error handling code of smsusb_init_device. Fix this by moving error handling code at the end of smsusb_init_device and adding a goto statement in the following error handling parts.

If fwnode_graph_get_remote_endpoint() fails, 'fwnode' is known to be NULL, so fwnode_handle_put() is a no-op. Release the reference taken from a previous fwnode_graph_get_port_parent() call instead. Also handle fwnode_graph_get_port_parent() failures. In order to fix these issues, add an error handling path to the function and the needed gotos.

An ATR is a device that looks similar to an i2c-mux: it has an I2C slave "upstream" port and N master "downstream" ports, and forwards transactions from upstream to the appropriate downstream port. But it is different in that the forwarded transaction has a different slave address. The address used on the upstream bus is called the "alias" and is (potentially) different from the physical slave address of the downstream chip. Add a helper file (just like i2c-mux.c for a mux or switch) to allow implementing ATR features in a device driver. The helper takes care of adapter creation/destruction and translates addresses at each transaction. Signed-off-by:

The supported ad5820 and ad5821 VCMs both use a single 16 bit register which is written by sending 2 bytes with the data directly after sending the i2c-client address. The ad5823 OTOH has a more typical i2c / smbus device setup with multiple 8 bit registers where the first byte send after the i2c-client address is the register address and the actual data only starts from the second byte after the i2c-client address. The ad5823 i2c_ and of_device_id-s was added at the same time as the ad5821 ids with as rationale: """ Some camera modules also refer that AD5823 is a replacement of AD5820: https://download.kamami.com/p564094-OV8865_DS.pdf """ The AD5823 may be an electrical and functional replacement of the AD5820, but from a software pov it is not compatible at all and it is going to need its own driver, drop its id from the ad5820 driver.

OV5640 will output abnormal image data when work at low resolution (320x240, 176x144 and 160x120) after switching from high resolution, such as 1080P, the time interval between high and low switching must be less than 1000ms in order to OV5640 don't enter suspend state during the time. The reason is by 0x3824 value don't restore to initialize value when do resolution switching. In high resolution setting array, 0x3824 is set to 0x04, but low resolution setting array remove 0x3824 in commit db15c195 ("media: ov5640: Remove duplicated mode settings"). So when do resolution switching from high to low, such as 1080P to 320x240, and the time interval is less than auto suspend delay time which means global initialize setting array will not be loaded, the output image data are abnormal. Hence move 0x3824 from ov5640_init_setting[] table to ov5640_setting_low_res[] table and also move 0x4407 0x460b, 0x460c to avoid same issue.
