Subject: Re: fix suspend/resume irq request free for yenta..
Date: Sun, 24 Jul 2005 01:46:29 +0200	[thread overview]
Message-ID: <200507240146.30670.daniel.ritz@gmx.ch> (raw)

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.
