From 0b82684c3c19aff092bb303959a31dbe5c965922 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Sun, 13 Apr 2008 16:03:38 +0200 Subject: [PATCH] sdhci: improve no card, no reset quirk The quirk was meant to just inhibit some resets, but ended up blocking all of them. Fortunately, this was just what was needed. Change the comment to reflect reality. Also, this issue has just been observed on Samsung laptops, so reduce the number of chips the quirk affects.
