Neaten current uses of dev_<level> by adding and using hid specific hid_<level> macros. Convert existing uses of dev_<level> uses to hid_<level>. Convert hid-pidff printk uses to hid_<level>. Remove err_hid and use hid_err instead. Add missing newlines to logging messages where necessary. Coalesce format strings. Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt Other miscellaneous changes: Add const struct hid_device * argument to hid-core functions extract() and implement() so hid_<level> can be used by them. Fix bad indentation in hid-core hid_input_field function that calls extract() function above. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
