Subject: [PATCH AUTOSEL 4.9 14/16] ACPI: AMBA: Fix resource name in /proc/iomem
Date: Sat, 10 Jul 2021 19:52:38 -0400 [thread overview]
Message-ID: <20210710235240.3222618-14-sashal@kernel.org> (raw)
In-Reply-To: <20210710235240.3222618-1-sashal@kernel.org>
From: Liguang Zhang <zhangliguang@linux.alibaba.com>
[ Upstream commit 7718629432676b5ebd9a32940782fe297a0abf8d ]
In function amba_handler_attach(), dev->res.name is initialized by
amba_device_alloc. But when address_found is false, dev->res.name is
assigned to null value, which leads to wrong resource name display in
/proc/iomem, "<BAD>" is seen for those resources.
