Subject: [PATCH] capabilities:: annotate implicit fall through
Date: Mon, 14 Jan 2019 21:28:35 +0100	[thread overview]
Message-ID: <20190114202835.15878-1-malat@debian.org> (raw)

There is a plan to build the kernel with -Wimplicit-fallthrough and
this place in the code produced a warning (W=1).

In this particular case change put the fall through comment on a single
line so as to match the regular expression expected by GCC.

This commit remove the following warning:

  kernel/capability.c:95:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
