Re: [PATCH] cifs: fix checkpatch warnings and normalize strings
From: Steve French
Date: Thu May 09 2019 - 01:14:44 EST
Merged into cifs-2.6.git for-next with minor cleanup. I also
(ironically) had to change the patch title since
checkpatch complained about mentioning "checkpatch" in the patch name.
Also FYI - since it didn't merge cleanly, I had to add one of the
changes manually as a distinct patch. See attached.
