| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | This includes a hack for the device as it returns only 0xff after a new firmware is loaded. To quote Mauro: "When the [...] firmware that came with the device is replaced by a new one, any I2C data received from the tuner will be replaced by 0xff. Probably, the vendor firmware has some patch specifically designed for this device. So, we can't replace by the generic firmware. The right solution would be to extract the [...] firmware from the original driver and ask the driver to load the specifically designed firmware, but, while we don't have that, the next best solution is to just keep the original firmware at the device."

| | | | | | | | | | | | | Reverts commit 3ab25123373270152a9fae98e3c48ef1b2a878c0 [media] af9035: override tuner for AVerMedia A835B devices Original commit itself is correct, but it was replaced by more general solution (commit 1cbbf90d0406913ad4b44194b07f4f41bde84e54). This old solution was committed by a accident and is not needed anymore. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | | Tuner ID set into EEPROM is wrong, which causes driver to select wrong tuner profile. That leads device non-working. Fix issue by overriding known bad tuner IDs with suitable default value. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
