Subject: nvme-fabrics: don't check for non-NULL module in nvmf_register_transport
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5a1e59533380a3fd04593e4ab2d4633ebf7745c1;p=openwrt%2Fstaging%2Fblogic.git

nvme-fabrics: don't check for non-NULL module in nvmf_register_transport

THIS_MODULE evaluates to NULL when used from code built into the kernel,
thus breaking built-in transport modules.  Remove the bogus check.

Fixes: 0de5cd36 ("nvme-fabrics: protect against module unload during create_ctrl")
