From d008b3d2be4b00267e7af5c21269e7af4f65c6e2 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 21 May 2019 12:42:56 +0300 Subject: mISDN: Fix indenting in dsp_cmx.c We used a script to indent this code back in 2012, but I guess it got confused by the ifdefs and added some extra tabs. This patch removes them. Signed-off-by: Dan Carpenter Signed-off-by: David S.
