[PATCH 0/6] bus: fsl-mc: Make remove function return void

[Uwe Kleine-König]

Hello,

many bus remove functions return an integer which is a historic
misdesign that makes driver authors assume that there is some kind of
error handling in the upper layers. This is wrong however and returning
and error code only yields an error message.

This series improves the fsl-mc bus by changing the remove callback to
return no value instead. As a preparation all drivers are changed to
return zero before so that they don't trigger the error message.

Best regards
Uwe
