Subject: [PATCH 3/6] staging: vc04_services: move client dbg directory into static variable
Date: Fri,  1 Jun 2018 13:10:01 +0200	[thread overview]
Message-ID: <20180601111004.1670-3-gregkh@linuxfoundation.org> (raw)
In-Reply-To: <20180601111004.1670-1-gregkh@linuxfoundation.org>

This does not need to be part of a wrapper function, or in a structure,
just properly reference it directly as a single variable.

The whole variable will be going away soon anyway, this is just a step
toward that direction.
