From: Christian Lamparter Date: Wed, 15 Oct 2008 01:55:37 +0000 (+0200) Subject: p54: broken out edcf changes X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0fdd7c5d2defe8c6873eb8a40a880eb0dc59573d;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git p54: broken out edcf changes This patch series hopefully increases p54's "longterm" stability.
