Subject: dmaengine: omap-dma: use devm_kzalloc() to allocate omap_dmadev.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=104fce73fdbd174eb08a493eeb2920fd59e6d3f4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: omap-dma: use devm_kzalloc() to allocate omap_dmadev.

Use devm_kzalloc() to allocate omap_dmadev() so that we don't need
complex error cleanup paths.
