Subject: [PATCH 02/14] PCI: aardvark: Fix return value of MSI domain .alloc() method
Date: Tue, 12 Oct 2021 18:41:33 +0200 [thread overview]
Message-ID: <20211012164145.14126-3-kabel@kernel.org> (raw)
In-Reply-To: <20211012164145.14126-1-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.
Fixes: f21a8b1b6837 ("PCI: aardvark: Move to MSI handling using generic MSI support")
