In several hid drivers it is necessary to calculate the length of an hid_report. This patch exports the existing static function hid_report_len of hid-core.c as an inline function in hid.h Signed-off-by: Mathieu Magnaudet <mathieu.magnaudet@enac.fr> Reviewed-by: Benjamin Tissoires <benjamin.tissoires@gmail.com> Reviewed-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
