Subject: [PATCH AUTOSEL 5.15 11/50] media: iommu/mediatek: Return ENODEV if the device is NULL
Date: Wed, 30 Mar 2022 07:49:25 -0400 [thread overview]
Message-ID: <20220330115005.1671090-11-sashal@kernel.org> (raw)
In-Reply-To: <20220330115005.1671090-1-sashal@kernel.org>
From: Yong Wu <yong.wu@mediatek.com>
[ Upstream commit 2fb0feed51085db77606de9b9477c96894328809 ]
The platform device is created at:
of_platform_default_populate_init: arch_initcall_sync
->of_platform_populate
->of_platform_device_create_pdata
When entering our probe, all the devices should be already created.
if it is null, means NODEV. Currently we don't get the fail case.
It's a minor fix, no need add fixes tags.
