From b88bd95655c7bc059606529e01467594978d7b72 Mon Sep 17 00:00:00 2001 From: Tilman Schmidt Date: Wed, 13 May 2009 12:44:18 +0000 Subject: gigaset: remove UNDOCREQ config option Drop the kernel config option GIGASET_UNDOCREQ, permanently activating the code it controlled, as there have been no reports of problems caused by its activation but many problems caused by it being disabled. Also fix a few bad comments while we're at it. Impact: cleanup Signed-off-by: Tilman Schmidt Signed-off-by: David S.
