Merge branch 'trivial' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/bkl
* 'trivial' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/bkl: block: autoconvert trivial BKL users to private mutex drivers: autoconvert trivial BKL users to private mutex ipmi: autoconvert trivial BKL users to private mutex mac: autoconvert trivial BKL users to private mutex mtd: autoconvert trivial BKL users to private mutex scsi: autoconvert trivial BKL users to private mutex Fix up trivial conflicts (due to addition of private mutex right next to deletion of a version string) in drivers/char/pcmcia/cm40[04]0_cs.c
