Subject: [PATCH v4 22/25] drm: kirin: Make driver_data variable non-global
Date: Mon, 19 Aug 2019 23:03:18 +0000 [thread overview]
Message-ID: <20190819230321.56480-23-john.stultz@linaro.org> (raw)
In-Reply-To: <20190819230321.56480-1-john.stultz@linaro.org>
From: Xu YiPing <xuyiping@hisilicon.com>
As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes the driver_data
value to not be a global variable. Instead the driver_data value
is accessed via the of_device_get_match_data() when needed.
