Some handlers (lirc for example) allocates memory on initialization,

Fixes warning about sleeping function in atomic context.

You should not replace it by a mutex, as the decoding code may happen during
IRQ time on several drivers.

If lirc is allocating memory, it should be using GFP_ATOMIC to avoid sleeping.
