hwmon: (dme1737) cleanups
This patch cleans up and prepares the dme1737 driver for support of the sch311x chips. (Almost) no functional changes. - Replaced whitespaces with tabs. - Removed empty lines. - Added _i2c_ to names of functions that are strictly I2C related. - Added 4 new functions: dme1737_create_files, dme1737_remove_files, dme1737_sio_enter, and dme1737_sio_exit. - Added error messages in case client attach/detach fails. Signed-off-by: Juerg Haefliger <juergh at gmail.com> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
