Subject: [PATCH] dma-buf: heaps: init heaps in subsys_initcall
Date:   Thu, 21 Oct 2021 14:16:07 +0800

Some built-in modules will failed to use dma-buf heap to allocate
memory if the heap drivers is too late to be initialized.
To fix this issue, move initialization of dma-buf heap drivers in
subsys_initcall() which is more earlier to be called.
