From: Joe Perches Date: Fri, 2 Sep 2016 22:58:01 +0000 (-0700) Subject: hso: Use a more common logging style X-Git-Tag: MMI-PSA29.97-13-9~7063^2~286^2~1 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=95a691179725fb8b3463d4d0f09a4d77e3c6f808;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git hso: Use a more common logging style Macros that end in an underscore are just odd. Add hso_dbg(level, fmt, ...) and use it everwhere instead. Several uses had additional unnecessary newlines as the macro added a newline. Remove the newline from the macro and add newlines to each use as appropriate. Remove now unused D macros. Signed-off-by: Joe Perches Signed-off-by: David S.
