Subject: media: nuvoton: npcm-video: Fix IS_ERR() vs NULL bug
Author: Dan Carpenter <dan.carpen...@linaro.org>
Date: Wed Sep 27 15:39:43 2023 +0300
The of_parse_phandle() function returns NULL on error. It never returns
error pointers. Update the check accordingly.
Fixes: 70721089985c ("media: nuvoton: Add driver for NPCM video capture and
encoding engine")
