[PATCH] ARM: 2785/1: S3C24XX - serial calls request_irq() with IRQs disabled
Patch from Ben Dooks
The request_irq() function is called by s3c24xx uart driver with
the local IRQs disabled. The request_irq() function can allocate
memory via kmalloc(), and this may sleep causing a warning about
sleeping in an invalid context.
