[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.
