Subject: [PATCH stable 4.9 12/21] media: dvb_frontend: get rid of property cache's state
Date: Fri, 5 Jun 2020 09:25:09 -0700 [thread overview]
Message-ID: <20200605162518.28099-13-florian.fainelli@broadcom.com> (raw)
In-Reply-To: <20200605162518.28099-1-florian.fainelli@broadcom.com>
From: Mauro Carvalho Chehab <mchehab@s-opensource.com>
commit ef2cc27cf860b79874e9fde1419dd67c3372e41c upstream
In the past, I guess the idea was to use state in order to
allow an autofush logic. However, in the current code, it is
used only for debug messages, on a poor man's solution, as
there's already a debug message to indicate when the properties
got flushed.
So, just get rid of it for good.
