From 28926994e5d7f049807119c48bd7b94c2d15fc95 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Thu, 13 Feb 2020 09:54:00 +0100 Subject: usb: host: fhci-hcd: annotate PIPE_CONTROL switch case with fallthrough After this was made buildable for something other than PPC32, kbuild starts warning drivers/usb/host/fhci-hcd.c:398:8: warning: this statement may fall through [-Wimplicit-fallthrough=] I don't know this code, but from the construction (initializing size with 0 and explicitly using "size +=" in the PIPE_BULK case) I assume that fallthrough is indeed intended.
