The cx231xx_get_i2c_adap() function should return the I2C adapter that will be used to talk with a device. It should never be NULL, as otherwise the driver will try to dereference a null pointer. We might instead fix the callers, but if this condition ever happens, it is really a driver bug, because i2c_port should always be a value from enum CX231XX_I2C_MASTER_PORT. Found when checking the code due to this bug: [ 39.769021] BUG: unable to handle kernel NULL pointer dereference at 0000000000000002 [ 39.769105] IP: [<ffffffff81638393>] i2c_master_send+0x13/0x70 Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> |
