From 5b0c942f8919ed962699a44e0abb4f8a599c52c1 Mon Sep 17 00:00:00 2001 From: Jongman Heo Date: Sun, 3 Jun 2012 21:32:13 +0000 Subject: [PATCH] mmc: fix wrong timeout check in mmc_send_status() (!timeout) condition check in mmc_send_status() can never be met, because do-while loop ends up with negative timeout value, -1. Fix the check to handle TIMEOUT case correctly.
