[PATCH 0/8] iio: Improve error reporting for problems during .remove for various i2c drivers

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

Hello,

the goal of this series is to improve the error messages emitted by
remove callbacks by several i2c drivers. The status quo is that these
might return an error code silently to the i2c core on remove. The
effect is a very unhelpful message:

	$bus $device: remove failed (EIO), will be ignored

. Note there is no further error handling and the device will be
removed, all devm cleanups are called.

With the patches from this series applied the emitted message better
tells what actually failed and the remove callback returns zero
unconditionally.

The motivation for this change is to make i2c remove callbacks return
void. The ability to return a value is misleading as driver authors
might expect some kind of error handling from the i2c core.

Best regards
Uwe
