Subject: [PATCH 05/11] arm: mediatek: force type of mtk_smp_base
Date: Tue,  8 Oct 2019 13:34:47 +0100	[thread overview]
Message-ID: <20191008123453.1651-5-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <20191008123453.1651-1-ben.dooks@codethink.co.uk>

In __mtk_smp_prepare_cpus force the return of phys_to_virt()
to have __iomem on it to avoid the following sparse warning:

arch/arm/mach-mediatek/platsmp.c:105:30: warning: incorrect type in assignment (different address spaces)
arch/arm/mach-mediatek/platsmp.c:105:30:    expected void [noderef] <asn:2> *static [toplevel] mtk_smp_base
arch/arm/mach-mediatek/platsmp.c:105:30:    got void *
