Subject: [PATCH AUTOSEL 4.9 04/13] scsi: advansys: Fix kernel pointer leak

From: Guo Zhi <qtxuning1999@...u.edu.cn>

[ Upstream commit d4996c6eac4c81b8872043e9391563f67f13e406 ]

Pointers should be printed with %p or %px rather than cast to 'unsigned
long' and printed with %lx.

Change %lx to %p to print the hashed pointer.
