Subject: [PATCH 11/18] ptp: fix missing break in switch

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Tue, 17 Jul 2018 20:17:33 -0500

[ 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")
