[PATCH 00/13] Make some spi device drivers return zero in .remove()

[Uwe Kleine-König]

Hello,

this series is part of my new quest to make spi remove callbacks return
void. Today they return an int, but the only result of returning a
non-zero value is a warning message. So it's a bad idea to return an
error code in the expectation that not freeing some resources is ok
then. The same holds true for i2c and platform devices which benefit en
passant for a few drivers.

The patches in this series address some of the spi drivers that might
return non-zero and adapt them accordingly to return zero instead. For
most drivers it's just about not hiding the fact that they already
return zero.

Given that there are quite some more patches of this type to create
before I can change the spi remove callback, I suggest the respecive
subsystem maintainers pick up these patches. There are no
interdependencies in this series.
