Linus, looks like we now have a new build warning in Linux next
with the fixes and raw_spinlock_t change, so a merge or a commit
is needed. If you prefer a patch, here's one below.

Subject: [PATCH] gpio: omap: Fix build warning for raw_spinlock_t conversion
and unlock fix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Looks like we now have a new build warning in Linux next with fix
977bd8a94c40 ("gpio: omap: add missed spin_unlock_irqrestore in
omap_gpio_irq_type") and raw_spinlock changes done in commit
4dbada2be460 ("gpio: omap: use raw locks for locking"):
drivers/gpio/gpio-omap.c: In function ‘omap_gpio_irq_type’:
drivers/gpio/gpio-omap.c:504:26: warning: passing argument 1 of
‘spin_unlock_irqrestore’ from incompatible pointer type
[-Wincompatible-pointer-types]
spin_unlock_irqrestore(&bank->lock, flags);

‘raw_spinlock_t * {aka struct raw_spinlock *}’
Fix the issue with using raw_spinlock_t instead.
