Subject: dmaengine: Move dma_get_slave_caps() implementation to dmaengine.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d5484b1c3db8a3870c6100deeb4678594433b2c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: Move dma_get_slave_caps() implementation to dmaengine.c

The function is too big to be a static inline.
