Subject: lib/genalloc.c: fix the end addr check in addr_in_gen_pool()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ad3d5d2f7deca6d0fd72163573bcb0cca6337e33;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

lib/genalloc.c: fix the end addr check in addr_in_gen_pool()

Since chunk->end_addr is (chunk->start_addr + size - 1), the end address
to compare should be (start + size - 1).
