From 436db5ce0d0e892d2f7327dd7ffd573c5fb9e6cb Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 24 Dec 2015 10:23:03 +0300 Subject: [PATCH] ACPI / debugger: remove some unneeded conditions "count" is unsigned so checking for less than zero here causes a static checker warning. And really it's better to let the access_ok() check fail if the user passes in a NULL "buf" pointer because -EFAULT is the correct error code. Signed-off-by: Dan Carpenter Signed-off-by: Rafael J.
