Subject: [PATCH AUTOSEL 5.4 264/350] spi: pxa2xx: Add missed security checks
Date: Tue, 10 Dec 2019 16:06:09 -0500 [thread overview]
Message-ID: <20191210210735.9077-225-sashal@kernel.org> (raw)
In-Reply-To: <20191210210735.9077-1-sashal@kernel.org>
From: Chuhong Yuan <hslester96@gmail.com>
[ Upstream commit 5eb263ef08b5014cfc2539a838f39d2fd3531423 ]
pxa2xx_spi_init_pdata misses checks for devm_clk_get and
platform_get_irq.
Add checks for them to fix the bugs.
Since ssp->clk and ssp->irq are used in probe, they are mandatory here.
So we cannot use _optional() for devm_clk_get and platform_get_irq.
