From 51c5d8d1499b8442e863fe756f76e7f4ea7476fb Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Thu, 4 Aug 2011 16:49:03 +0100 Subject: [PATCH] mmc: at91_mci: remove the use of irq_to_gpio Remove the use of irq_to_gpio() in the card detection interrupt handler. The information is available in the board structure and we can avoid using a function that has little meaning.
