[PATCH 5.4 015/100] scsi: advansys: Fix kernel pointer leak
From: Greg Kroah-Hartman
Date: Wed Nov 24 2021 - 08:19:28 EST
From: Guo Zhi <qtxuning1999@xxxxxxxxxxx>
[ 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.
