X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84a08fa9eb330969b661305bd5a5fcae06d98cba;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git Staging: ipack/bridges/tpci200: Store beginning of module memory regions in struct tpci200. tpci200_register is converted to use this. A later patch will build on this.
