From 3181c38e4df257852a0c0a53552fd5c869402886 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 3 Oct 2017 16:16:07 -0700 Subject: [PATCH] kernel/sysctl.c: remove duplicate UINT_MAX check on do_proc_douintvec_conv() do_proc_douintvec_conv() has two UINT_MAX checks, we can remove one. This has no functional changes other than fixing a compiler warning: kernel/sysctl.c:2190]: (warning) Identical condition '*lvalp>UINT_MAX', second condition is always false Fixes: 4f2fec00afa60 ("sysctl: simplify unsigned int support") Link: http://lkml.kernel.org/r/20170919072918.12066-1-mcgrof@kernel.org Signed-off-by: Luis R.
