Subject: net: socket: Fix missing break in switch statement
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=60747828eac28836b49bed214399b0c972f19df3;p=linux.git

net: socket: Fix missing break in switch statement

Add missing break statement in order to prevent the code from falling
through to cases SIOCGSTAMP_NEW and SIOCGSTAMPNS_NEW.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.

Fixes: 0768e17073dc ("net: socket: implement 64-bit timestamps")
