drm/i2c: tda9950: set MAX_RETRIES for errors only
The CEC_TX_STATUS_MAX_RETRIES should be set for errors only to prevent the CEC framework from retrying the transmit. If the transmit was successful, then don't set this flag. Found by running 'cec-compliance -A' on a beaglebone box. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
