Subject: [PATCH] media: tc358743: cleanup tc358743_cec_isr
Date: Wed, 2 Sep 2020 11:32:12 -0700 [thread overview]
Message-ID: <20200902183212.4928-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
tc358743_cec_isr is misnammed, it is not the main isr.
So rename it to be consistent with its siblings,
tc358743_cec_handler.
It also does not check if its input parameter 'handled' is
is non NULL like its siblings, so add a check.
Fixes: a0ec8d1dc42e ("media: tc358743: add CEC support")
