Subject: geneve: Unregister pernet subsys on module unload.
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d3ca9eafc0ed97b8f56fdf23655cfece89c48354;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

geneve: Unregister pernet subsys on module unload.

The pernet ops aren't ever unregistered, which causes a memory
leak and an OOPs if the module is ever reinserted.

Fixes: 0b5e8b8eeae4 ("net: Add Geneve tunneling protocol driver")
