Subject: [RESEND PATCH v3 3/3] PCI: vmd: Replace pci_alloc_irq_vectors() with pcim_alloc_irq_vectors()
Date: Wed, 22 Apr 2026 10:38:42 +0800	[thread overview]
Message-ID: <1776825522-6390-4-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1776825522-6390-1-git-send-email-shawn.lin@rock-chips.com>

Replace pci_alloc_irq_vectors() with pcim_alloc_irq_vectors() to
explicitly request devres-managed interrupt vectors. This makes the
driver's intention clear and avoids the ambiguous implicit management
previously provided by pcim_enable_device().

The change prepares the driver for the eventual removal of the hybrid
IRQ management pattern from pcim_enable_device(), ensuring consistent
resource management through devres.
