device: Add #define dev_fmt similar to #define pr_fmt
Add a prefixing macro to dev_<level> uses similar to the pr_fmt prefixing macro used in pr_<level> calls. This can help avoid some string duplication in dev_<level> uses. The default, like pr_fmt, is an empty #define dev_fmt(fmt) fmt Rename the existing dev_<level> functions to _dev_<level> and introduce #define dev_<level> _dev_<level> macros that use the new #define dev_fmt Miscellanea: o Consistently use #defines with fmt, ... and ##__VA_ARGS__ o Remove unnecessary externs Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
