Subject: [PATCH] media: tc358743: cleanup tc358743_cec_isr
Git-commit: 877cb8a444dad2304e891294afb0915fe3c278d6
Patch-mainline: v5.10-rc1
References: git-fixes

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")
