Subject: hfsplus: fix bug causing custom uid and gid being unable to be assigned with mount
From: Aditya Garg <gargaditya08@xxxxxxxx>
commit 9f2b5debc07073e6dfdd774e3594d0224b991927 upstream.
Despite specifying UID and GID in mount command, the specified UID and GID
were not being assigned. This patch fixes this issue.
