Subject: [PATCH] arm64: kexec_file: Fix sparse warning
Date: Mon, 9 Nov 2020 11:11:37 +0000 [thread overview]
Message-ID: <20201109111137.14134-1-will@kernel.org> (raw)
Sparse gets cross about us returning 0 from image_load(), which has a
return type of 'void *':
>> arch/arm64/kernel/kexec_image.c:130:16: sparse: sparse: Using plain integer as NULL pointer
Return NULL instead, as we don't use the return value for anything if it
does not indicate an error.
