SubjectRe: fix suspend/resume irq request free for yenta..
Date
hi

the patch is wrong. yenta_request_irq() registers the wrong handler.
plus yenta_probe_cb_irq() has nothing to do with suspend/resume
(besides it frees the irq in the very same function). correct patch below.

somebody cares to explain me why the free_irq() is necessary before
a suspend?

[PATCH] yenta: free_irq() on suspend.

Resume doesn't seem to work without.
