Obviously I was wrong and introduced build problems with the following patches: input: touchscreen: tsc200x: Make tsc200x_remove() return void mfd: mc13xxx: Make mc13xxx_common_exit() return void serial: max310x: Make max310x_remove() return void serial: sc16is7xx: Make sc16is7xx_remove() return void Please don't apply these (unless you also fix the trivial problems in them). I will prepare a v2 soon. Best regards and sorry for the inconvenience, Uwe
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.
