Subject: [PATCH] staging: comedi: pcmmio: use pcmmio_dio_{read, write}() in
 interrupt_pcmmio()

Use the helper functions to read/write the PCMMIO_PAGE_INT_ID registers. This
allows removing the need to lock/unlock the spinlock 'pagelock' and removes the
need for the for () loop that did the read/write of the 3 paged registers.

Also, remove the need for the 'got1' local variable by just returning 'IRQ_NONE'
if there are not interrupts pending.
