[PATCH 5/5] um: process: remove unused 'n' variable

[Johannes Berg]

From: Johannes Berg <johannes.b...@intel.com>

The return value of fn() wasn't used for a long time,
so no need to assign it to a variable, addressing a
W=1 warning.

This seems to be - with patches from others posted to
the list before - the last W=1 warning in arch/um/.

Fixes: 22e2430d60db ("x86, um: convert to saner kernel_execve() semantics")
Signed-off-by: Johannes Berg <johannes.b...@intel.com>
