[PATCH 4.8 26/92] staging: nvec: remove managed resource from PS2 driver

From: Greg Kroah-Hartman
Date: Thu Nov 17 2016 - 06:03:14 EST

4.8-stable review patch. If anyone has any objections, please let me know.


From: Marc Dietrich <marvin24@xxxxxx>

commit 68fae2f3df455f53d0dfe33483a49020b3b758f3 upstream.

This basicly reverts commit e534f3e9 (staging:nvec: Introduce the use of
the managed version of kzalloc). Serio struct should never by managed
because it is refcounted. Doing so will lead to a double free oops on module
