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). Signed-off-by: Toshi Kikuchi <toshik@chromium.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
