From b52e111363e366202386f3e67f71681dbbb8e5d9 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 1 Nov 2013 09:17:50 -0700 Subject: Revert "pl2303: improve the chip type information output on startup" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit a77a8c23e4db9fb1f776147eda0d85117359c700. Revert all of the pl2303 changes that went into 3.12-rc1 and -rc2 as they cause regressions on some versions of the chip. This will all be revisited for later kernel versions when we can figure out how to handle this in a way that does not break working devices.
