[PATCH 3.16 096/233] net: ethernet: ax88796: don't call free_irq without request_irq first

Show all headers | View raw

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

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

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

commit 82533ad9a1ce3a7a6863849a552c2cc041b55e0d upstream.

The function ax_init_dev (which is called only from the driver's .probe
function) calls free_irq in the error path without having requested the
irq in the first place. So drop the free_irq call in the error path.

Fixes: 825a2ff1896e ("AX88796 network driver")
