Subject[PATCH 4.14 031/164] firmware: vpd: Destroy vpd sections in remove function
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guenter Roeck <linux@roeck-us.net>

commit 811d7e0215fb738fb9a9f0bcb1276516ad161ed1 upstream.

vpd sections are initialized during probe and thus should be destroyed
in the remove function.

Fixes: 049a59db34eb ("firmware: Google VPD sysfs driver")
