From c4a72cbdb39fd559988b16d118f7e5782935ff11 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 10 Sep 2005 11:58:21 +0100 Subject: [MMC] Add mmc_detect_change() delay support for wbsd driver Convert wbsd to use the new delay functionality in mmc_detect_change() rather than implementing its own timer.
