Subject: [PATCH -next] dma-buf: heaps: Make sys_heap static
Date:   Thu, 29 Oct 2020 20:10:43 +0800

Fix the following sparse warning:

drivers/dma-buf/heaps/system_heap.c:23:17: warning: symbol 'sys_heap' was not declared. Should it be static?

sys_heap has only call within system_heap.c
It should be static
