spi: make remove callback a void function
Merge series from Uwe Kleine-König <u.kleine-koenig@pengutronix.de>: this series goal is to change the spi remove callback's return value to void. After numerous patches nearly all drivers already return 0 unconditionally. The four first patches in this series convert the remaining three drivers to return 0, the final patch changes the remove prototype and converts all implementers. base-commit: 26291c54e111ff6ba87a164d85d4a4e134b7315c
