Subject: [PATCH 1/2] csky: Cast argument to virt_to_pfn() to (void *)
Date: Tue, 08 Aug 2023 10:25:55 +0200	[thread overview]
Message-ID: <20230808-csky-virt-to-phys-v1-1-ac727f8def2f@linaro.org> (raw)
In-Reply-To: <20230808-csky-virt-to-phys-v1-0-ac727f8def2f@linaro.org>

The virt_to_pfn() function takes a (void *) as argument, fix
this up to avoid exploiting the unintended polymorphism of
virt_to_pfn.
