4.14-stable review patch. If anyone has any objections, please let me know.

From: "Gustavo A. R. Silva" <gustavo@xxxxxxxxxxxxxx>
[ Upstream commit 9ba8376ce1e2cbf4ce44f7e4bee1d0648e10d594 ]
It seems that a *break* is missing in order to avoid falling through
to the default case. Otherwise, checking *chan* makes no sense.
Fixes: 72df7a7244c0 ("ptp: Allow reassigning calibration pin function")
