Subject: [PATCH v2 5/6] ALSA: hda: Use pci_is_display()
Date: Tue, 17 Jun 2025 12:59:09 -0500	[thread overview]
Message-ID: <20250617175910.1640546-6-superm1@kernel.org> (raw)
In-Reply-To: <20250617175910.1640546-1-superm1@kernel.org>

From: Mario Limonciello <mario.limonciello@amd.com>

The inline pci_is_display() helper does the same thing.  Use it.

Suggested-by: Bjorn Helgaas <helgaas@kernel.org>
