Subject: [65/70] ASoC: WM8903: Fix mic detection enable logic

2.6.37-stable review patch.  If anyone has any objections, please let us know.

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

From: Stephen Warren <swarren@...dia.com>

commit 3088e3b4963d26d6f6f54987f595b974ed6d48d8 upstream.

The mic detection HW should be enabled when either mic or short detection
is required, not when only both are required.
