From 27490ae6a85a70242d80615ca74d0362a820d6a7 Mon Sep 17 00:00:00 2001 From: Guo Zhi Date: Wed, 29 Sep 2021 20:25:37 +0800 Subject: [PATCH] scsi: advansys: Fix kernel pointer leak [ 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. Link: https://lore.kernel.org/r/20210929122538.1158235-1-qtxuning1999@sjtu.edu.cn Signed-off-by: Guo Zhi Signed-off-by: Martin K.
