Subject: [PATCH V4 06/10] PCI/VGA: Prefer vga_default_device()
Date: Fri, 27 Aug 2021 16:31:25 +0800	[thread overview]
Message-ID: <20210827083129.2781420-7-chenhuacai@loongson.cn> (raw)
In-Reply-To: <20210827083129.2781420-1-chenhuacai@loongson.cn>

Use the vga_default_device() interface consistently instead of directly
testing vga_default.  No functional change intended.

[bhelgaas: split to separate patch and extended]
