Subject: module: zero mod->init_ro_size after init is freed.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4d10380e720a3ce19dbe88d0133f66ded07b6a8f;p=linux-beck.git

module: zero mod->init_ro_size after init is freed.

Reset mod->init_ro_size to zero after the init part of a module is unloaded.
Otherwise we need to check if module->init is NULL in the unprotect functions
in the next patch.
