Subject: [PATCH v2 03/10] hid/hid-picolcd: Fix initialization order
Date: Wed, 21 Feb 2024 10:41:30 +0100	[thread overview]
Message-ID: <20240221094324.27436-4-tzimmermann@suse.de> (raw)
In-Reply-To: <20240221094324.27436-1-tzimmermann@suse.de>

For drivers that support backlight, LCD and fbdev devices, fbdev has
to be initialized last. See documentation for struct fbinfo.bl_dev.
