4.19-stable review patch. If anyone has any objections, please let me know.
------------------ From: Luis Chamberlain <mcg...@kernel.org> commit 5618cf031fecda63847cafd1091e7b8bd626cdb1 upstream. We free the misc device string twice on rmmod; fix this. Without this we cannot remove the module without crashing.
