From 0a335b6d47f014c41b8a0c8cbdc6d4886c10f5d5 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 24 Sep 2013 10:40:57 +0800 Subject: mmc: cb710: drop free_irq for devm_request_irq allocated irq irq allocated with devm_request_irq should not be freed using free_irq, because doing so causes a dangling pointer, and a subsequent double free.
