Subject: [RFC PATCH 5/8] drm/panel-simple: Copy "desc" into driver data; don't store a pointer
Date: Thu, 22 Jul 2021 17:21:43 -0700	[thread overview]
Message-ID: <20210722172104.RFC.5.I89640bdefeafa3b4a856f16fb7f150dc2c4b14d5@changeid> (raw)
In-Reply-To: <20210723002146.1962910-1-dianders@chromium.org>

Up until now "desc" has usually pointed to one of the "static const"
objects defined in the panel-simple driver. Just storing a pointer to
one of these data elements made sense.

In a future patch to support probable eDP panels, however, it's
convenient to be able to modify the delays that the driver uses as it
starts up. One nice way to handle this is to just copy the "desc" into
our driver data instead of storing a pointer.

This has a nice side effect of simplifying the "DPI" case since we no
longer need an extra alloc there.
