Subject: media: si21xx: report eventual errors at set_frontend Author: Mauro Carvalho Chehab <[email protected]> Date: Mon Nov 22 12:30:55 2021 +0000 If an error occurs while setting the registers at set_frontend, it is silently ignored. Yet, the variable status is updated. Change the logic to return an error if it fails to write values to the registers.
