From 0bd35534933feceb7afb383ce7947f2841132c99 Mon Sep 17 00:00:00 2001 From: Sean MacLennan Date: Sun, 15 Nov 2015 19:51:43 -0500 Subject: [PATCH] staging:rtl8192e: Usage count off by one The rtllib driver is not calling try_module_get() when loading the encryption modules. Because of this, you can never remove the module once you have used it one (i.e. bring up the wireless interface).
