Write procedure can't be interrupted by any signal

Dear Marcin,

I'm afraid, your write procedure can't be interrupted (via CTRL+C or sending any signal) in case of any hardware problems.
The reason is that you do not check the result of wait_event_interruptible in line:

nrf24/nrf24_if.c

Line 369 in b9b7ebd

wait_event_interruptible(p->write_wait_queue, p->write_done);

You should interrupt the write loop and report an error here.

With best regards,
Wojtek
