Message-ID: <20150129053316.GA2508@thunderCat> Date: Thu, 29 Jan 2015 13:33:17 +0800 From: Simon Guo <wei.guo.simon@...il.com> To: Ian Abbott <abbotti@....co.uk>, H Hartley Sweeten <hsweeten@...ionengravers.com>, Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org, wei.guo.simon@...il.com Subject: [PATCH v2 01/02] STAGING: Fix pcl818.c coding style issue: code indent should use tabs where possible Correct one coding style problem(detected by checkpatch.pl) in pcl818.c. - code indent should use tabs where possible It is fixed by reformatting the comment block to usual comment style. And with the reformatting, following coding style problem is also fixed: - please, no space before tabs Signed-off-by: Simon Guo <wei.guo.simon@...il.com> --- drivers/staging/comedi/drivers/pcl818.c | 189 +++++++++++++++----------------- 1 file changed, 91 insertions(+), 98 deletions(-) diff --git a/drivers/staging/comedi/drivers/pcl818.c b/drivers/staging/comedi/drivers/pcl818.c index ba2e137..5d9050c 100644 --- a/drivers/staging/comedi/drivers/pcl818.c +++ b/drivers/staging/comedi/drivers/pcl818.c @@ -1,102 +1,95 @@ /* - comedi/drivers/pcl818.c - - Author: Michal Dobes <dobes@...net.cz> - - hardware driver for Advantech cards: - card: PCL-818L, PCL-818H, PCL-818HD, PCL-818HG, PCL-818, PCL-718 - driver: pcl818l, pcl818h, pcl818hd, pcl818hg, pcl818, pcl718 -*/ -/* -Driver: pcl818 -Description: Advantech PCL-818 cards, PCL-718 -Author: Michal Dobes <dobes@...net.cz> -Devices: [Advantech] PCL-818L (pcl818l), PCL-818H (pcl818h), - PCL-818HD (pcl818hd), PCL-818HG (pcl818hg), PCL-818 (pcl818), - PCL-718 (pcl718) -Status: works - -All cards have 16 SE/8 DIFF ADCs, one or two DACs, 16 DI and 16 DO. -Differences are only at maximal sample speed, range list and FIFO -support. -The driver support AI mode 0, 1, 3 other subdevices (AO, DI, DO) support -only mode 0.
