X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5622ff1a4dd7dcb1c09953d8066a4e7c4c350b2d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

dma: edma: Remove limits on number of slots

With this series, this check is no longer required and
we shouldn't need to reject drivers DMA'ing more than the
MAX number of slots.
