drivers: video: gc2145: return 0 at the end of functions (9174cb75) · Commits · Wenxi XU / zephyr

After the error code is checked to be zero, it is possible to return 0 explicitly to help with readability. Also, when available, forward the return code from the failing function instead of a locally chosen error code like -EIO. Signed-off-by:
