Arnd Bergmann 7b8a3d22ba ataflop: fix sleep_on races ... sleep_on() is inherently racy, and has been deprecated for a long time. This fixes two instances in the atari floppy driver: * fdc_wait/fdc_busy becomes an open-coded mutex. We cannot use the regular mutex since it gets released in interrupt context. The open-coded version using wait_event() and cmpxchg() is equivalent to the existing code but does the checks atomically, and we can now safely check the condition with irqs enabled. * format_wait becomes a completion, which is the natural structure here. The format ioctl waits for the background task to either complete or abort. This does not attempt to fix the preexisting bug of calling schedule with local interrupts disabled.
