Subject: [PATCH 3.16 021/366] net-next: ax88796: Do not free IRQ in
 ax_remove() (already freed in ax_close()).

3.16.61-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Michael Karcher <kernel@...rcher.dialup.fu-berlin.de>

commit 9144c3795c2636351d553e4d0fc5297201182de2 upstream.

This complements the fix in 82533ad9a1c ("net: ethernet: ax88796:
don't call free_irq without request_irq first") that removed the
free_irq call in the error path of probe, to also not call free_irq
when remove is called to revert the effects of probe.

Fixes: 82533ad9a1c (net: ethernet: ax88796: don't call free_irq without request_irq first)
