[PATCH] regmap: use less #ifdef for LOG_DEVICE

From: Ben Dooks
Date: Tue Oct 02 2018 - 06:42:14 EST


Move the checking of the LOG_DEVICE into a function to reduce the
number of #ifdefs and ensure more of the code gets compiled/checked,
and make it easier to change this for internal debugging purposes
(such as checking >1 device).
