3.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pankaj Dubey <pankaj.du...@samsung.com>
commit 5336be8416a71b5568d2cf54a2f2066abe9f2a53 upstream.
If LOG_DEVICE is defined and map->dev is NULL it will lead to NULL
pointer dereference. This patch fixes this issue by adding check for
dev->NULL in all such places in regmap.c
