Subject: crypto: marvell/cesa - use dma_addr_t for cur_dma
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5d754137ab905aaaf69acf81c9c6c7005bcfe6e4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

crypto: marvell/cesa - use dma_addr_t for cur_dma

cur_dma is part of the software state, not read by the hardware.
Storing it in LE32 format is wrong, use dma_addr_t for this.
