Subject: [PATCH AUTOSEL 4.9 5/8] ACPI: LPSS: Fix missing check in register_device_clock()
Date: Sun,  7 Aug 2022 21:40:00 -0400	[thread overview]
Message-ID: <20220808014005.317064-5-sashal@kernel.org> (raw)
In-Reply-To: <20220808014005.317064-1-sashal@kernel.org>

From: huhai <huhai@kylinos.cn>

[ Upstream commit b4f1f61ed5928b1128e60e38d0dffa16966f06dc ]

register_device_clock() misses a check for platform_device_register_simple().
Add a check to fix it.
