From e633b7bcec8e26991d489a11615acf7674efbaf4 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Sun, 31 Aug 2008 13:38:54 +0200 Subject: [PATCH] sdio: make sleep on error interruptable Make sure we can be woken from the forced sleep that is done on errors. Removing a card often results in -ENOMEDIUM or -EILSEQ so we previously locked up the removal process for a second. We could completely exit on -ENOMEDIUM, but it might be a transient glitch so treat it like any other error.
