Subject: can: c_can: precedence error in c_can_chip_config()
From: Dan Carpenter <[email protected]>
commit d9cb9bd63eb27ac19f26a8547128c053f43a5da8 upstream.
(CAN_CTRLMODE_LISTENONLY & CAN_CTRLMODE_LOOPBACK) is (0x02 & 0x01) which
is zero so the condition is never true. The intent here was to test
that both flags were set.
