Merge tag 'spi-remove-void' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Mark Brown says: ==================== spi: Make remove() return void This series from Uwe Kleine-König converts the spi remove function to return void since there is nothing useful that we can do with a failure and it as more buses are converted it'll enable further work on the driver core. ==================== Link: https://lore.kernel.org/r/20220228173957.1262628-2-broonie@kernel.org/ Signed-off-by: Jakub Kicinski <kuba@kernel.org>
