From 73778120c4088a0a7b59c4c378904f7a230b4820 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Sun, 22 Oct 2006 22:13:10 +0200 Subject: [PATCH] mmc: Fix mmc_delay() function Several fixes for mmc_delay(): * Repair if-clause that was supposed to detect sub-hz delays. * Change yield() to cond_resched() as yield() no longer has the semantics we desire. * mmc_delay() is used to guarantee protocol delays, so we cannot return early (i.e. use _interruptable). Based on patch by Amol Lad.
