Subject: [PATCH v1 -next 1/2] RISC-V: ACPI : Fix for usage of pointers in different address space
Date: Mon,  5 Jun 2023 20:05:11 +0530	[thread overview]
Message-ID: <20230605143512.707533-2-sunilvl@ventanamicro.com> (raw)
In-Reply-To: <20230605143512.707533-1-sunilvl@ventanamicro.com>

The arch specific __acpi_map_table can be wrapper around either
early_memremap or early_ioremap. But early_memremap
routine works with normal pointers whereas __acpi_map_table expects
pointers in iomem address space. This causes kernel test bot to fail
while using the sparse tool. Fix the issue by using early_ioremap and
similar fix done for __acpi_unmap_table.

Signed-off-by: Sunil V L <sunilvl@ventanamicro.com>
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202305201427.I7QhPjNW-lkp@intel.com/
