Subject: [PATCH 3.12 016/113] platform/x86: intel_mid_powerbtn: Set IRQ_ONESHOT

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

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

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

commit 5a00b6c2438460b870a451f14593fc40d3c7edf6 upstream.

The commit 1c6c69525b40 ("genirq: Reject bogus threaded irq requests")
starts refusing misconfigured interrupt handlers. This makes
intel_mid_powerbtn not working anymore.

Add a mandatory flag to a threaded IRQ request in the driver.

Fixes: 1c6c69525b40 ("genirq: Reject bogus threaded irq requests")
