Message-Id: <1447694308-7724-1-git-send-email-ranjithece24@gmail.com> Date: Mon, 16 Nov 2015 22:48:27 +0530 From: Ranjith Thangavel <ranjithece24@...il.com> To: gregkh@...uxfoundation.org Cc: abbotti@....co.uk, hsweeten@...ionengravers.com, devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org, ranjithece24@...il.com Subject: [PATCH 1/2] comedi: dmm32at: Fix coding style - use BIT macro BIT macro is used for defining BIT location instead of shifting operator, usleep_range is preferred over udelay - coding style issue Signed-off-by: Ranjith Thangavel <ranjithece24@...il.com> ---
