Subject: [PATCH] mfd: twl4030-irq: irq_desc->lock converted to raw_spinlock_t
commit 239007b8440abff689632f50cdf0f2b9e895b534 converted
the spinlock_t to raw_spinlock_t. Unfortunately twl4030-irq
was left aside on the conversion.

I'm not sure this is the expected fix since twl4030-irq handler
should be running in thread context. Currently mask/unmask/set_type
are deferred to a workqueue. Thomas, should this be done ? How
do you expect irq chips on slow busses to implement mask/unmask/set_type ?
