Subject: [PATCH AUTOSEL for 3.18 053/101] libertas: Fix
 lbs_prb_rsp_limit_set()

From: Dan Carpenter <dan.carpenter@...cle.com>

[ Upstream commit 69551f5f370cc20342fab17ca54716b6ec7e332d ]

The kstrtoul() test was reversed so this always returned -ENOTSUPP.

Fixes: 27d7f47756f4 ("net: wireless: replace strict_strtoul() with kstrtoul()")
