Subject: [PATCH v2 1/1] drm/rockchip: fix integer type used for storing dp data rate
Date: Thu, 9 Jan 2020 08:31:29 +0100 [thread overview]
Message-ID: <20200109073129.378507-2-t.schramm@manjaro.org> (raw)
In-Reply-To: <20200109073129.378507-1-t.schramm@manjaro.org>
commmit 2589c4025f13 ("drm/rockchip: Avoid drm_dp_link helpers") changes
the type of variables used to store the display port data rate and
number of lanes to u8. However u8 is not sufficient to store the link
data rate of the display port.
This commit reverts the type of data rate to unsigned int.
