Uwe Kleine-König c39cf60feb mfd: mc13xxx: Make mc13xxx_common_exit() return void
Up to now mc13xxx_common_exit() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.

Also the return value of i2c and spi remove callbacks is ignored anyway.
