Subject: [PATCH AUTOSEL 6.8 14/15] ata: sata_gemini: Check clk_enable() result
Date: Mon, 15 Apr 2024 06:02:54 -0400 [thread overview]
Message-ID: <20240415100311.3126785-14-sashal@kernel.org> (raw)
In-Reply-To: <20240415100311.3126785-1-sashal@kernel.org>
From: Chen Ni <nichen@iscas.ac.cn>
[ Upstream commit e85006ae7430aef780cc4f0849692e266a102ec0 ]
The call to clk_enable() in gemini_sata_start_bridge() can fail.
Add a check to detect such failure.
