[PATCH v3 01/23] linux/device.h: use DYNAMIC_DEBUG_BRANCH in dev_dbg_ratelimited

From: Rasmus Villemoes
Date: Fri Nov 09 2018 - 18:13:21 EST


dev_dbg_ratelimited tests the dynamic debug descriptor the old-fashioned
way, and doesn't utilize the static key/jump label implementation on
architectures that HAVE_JUMP_LABEL. Use the DYNAMIC_DEBUG_BRANCH which
is defined appropriately.
