From 6f4789e6a81f4678b8ffa73a6226be0f99955190 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Wed, 4 Jun 2014 12:42:11 +0100 Subject: [PATCH] mmc: sh-mmcif: use devm_ for irq management Use devm_request_threaded_irq() for the host interrupt handlers so we do not have to worry about freeing them on exit or error. Tidies up the exit path code for the driver.
