From: Dan Carpenter <dan.carpen...@oracle.com> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== [ Upstream commit 50010c20597d14667eff0fdb628309986f195230 ] This is decrementing the pointer, instead of the value stored in the pointer. KASan detects it as an out of bounds reference. Reported-by: "Berry Cheng 程君(成淼)" <chengmiao...@alibaba-inc.com> Signed-off-by: Dan Carpenter <dan.carpen...@oracle.com> Signed-off-by: David S.
