Subject: cbus: retu: drop the unnecessary spinlock_t
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b949ac29776023c007a316ec2e020f5916adc390;p=pandora-kernel.git

cbus: retu: drop the unnecessary spinlock_t

gpiolib functions can sleep, and we already
have a mutex on the driver, so drop the
spinlock_t and use the mutex.

While at that, also rename irq_lock to
mutex since that's not used only for the
IRQ path anymore.
