Subject: module: module_unload_init() cleanup
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2409e74278b7fb917d39ef6d3c16223c04a386f2;p=linux-beck.git

module: module_unload_init() cleanup

No need to clear mod->refptr in module_unload_init(), since
alloc_percpu() already clears allocated chunks.
