Subject: [PATCH 3.12 087/146] clk: vexpress: NULL dereference on error path

From: Dan Carpenter <dan.carpenter@...cle.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 6b4ed8b00e93bd31f24a25f59ed8d1b808d0cc00 upstream.

If the allocation fails then we dereference the NULL in the error path.
Just return directly.

Fixes: ed27ff1db869 ('clk: Versatile Express clock generators ("osc") driver')
