Subject: rapidio: replace rio_free_net() with kfree() in rio_scan_alloc_net()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=666183dcdd9ad3b8156a1df7f204f728f720380f;p=thirdparty%2Fkernel%2Flinux.git

rapidio: replace rio_free_net() with kfree() in rio_scan_alloc_net()

When idtab allocation fails, net is not registered with rio_add_net() yet,
so kfree(net) is sufficient to release the memory.  Set mport->net to NULL
to avoid dangling pointer.
