Subject: regmap: Fix work_buf switching for page update during virtual range access.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=632a5b01db8cd4068a06f8a67720ea4f9b00d9b3;p=deliverable%2Flinux.git

regmap: Fix work_buf switching for page update during virtual range access.

After page update, orginal work_buf has to be restored regardless of
the result.
