Subject: [NETFILTER]: x_tables: small check_entry & module_refcount cleanup
X-Git-Tag: v2.6.19-rc1~1272^2~39
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=90d47db4a06f93f7339618b2a4f0cb032ef8d6d5;p=linux-2.6

[NETFILTER]: x_tables: small check_entry & module_refcount cleanup

While standard_target has target->me == NULL, module_put() should be
called for it as for others, because there were try_module_get() before.
