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.
