[ARM] 4088/1: AT91: Unbalanced IRQ in serial driver suspend/resume
This patch fixes the unbalanced calls to enable_irq_wake() and
disable_irq_wake() in the AT91 (and AVR32) serial driver.
It should resolve these kernel messages:
Unbalanced IRQ x wake disable
BUG: warning at kernel/irq/manage.c:167/set_irq_wake()
Original patch from Marc Pignat.
