Subject: [PATCH v2 2/7] PCI: aardvark: Fix return value of MSI domain .alloc() method
Date: Thu, 28 Oct 2021 20:56:54 +0200	[thread overview]
Message-ID: <20211028185659.20329-3-kabel@kernel.org> (raw)
In-Reply-To: <20211028185659.20329-1-kabel@kernel.org>

MSI domain callback .alloc() (implemented by advk_msi_irq_domain_alloc()
function) should return zero on success, since non-zero value indicates
failure.

When the driver was converted to generic MSI API in commit f21a8b1b6837
("PCI: aardvark: Move to MSI handling using generic MSI support"), it
was converted so that it returns hwirq number.

Fix this.
