Subject: net: sfp: move sfp_register_socket call from sfp_remove to sfp_probe
X-Git-Tag: v4.14.112~69
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f5393c36705010563a97e3a73e28ace83ff515e0;p=people%2Farne_f%2Fkernel.git

net: sfp: move sfp_register_socket call from sfp_remove to sfp_probe

Commit c4ba68b8691e4 backported from upstream to 4.14 stable was
probably applied wrongly, and instead of calling sfp_register_socket in
sfp_probe, the socket registering code was put into sfp_remove. This is
obviously wrong.

The commit first appeared in 4.14.104. Fix it for the next 4.14 release.
