[PATCH] leds: is31fl32xx: Improve error reporting in .remove()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't make
a difference. The device goes away anyhow and the devm cleanups are
called.

So instead of triggering the generic i2c error message, emit a more helpful
message if a problem occurs and return 0 to suppress the generic message.

This patch is a preparation for making i2c remove callbacks return void.
