V4L/DVB (6214): usbvision: Don't support I2C_M_REV_DIR_ADDR
I2C adapters should only support I2C_M_REV_DIR_ADDR if they really have to (i.e. if they are connected to a broken I2C device which needs this deviation from the standard I2C protocol.) As no media chip driver uses I2C_M_REV_DIR_ADDR, I don't think that the usbvision driver needs to support it.
