Subject: [PATCH] dma-buf: really enable DMABUF_DEBUG by default on DEBUG kernels

From: Lukas Bulwahn <lukas.bulwahn@...hat.com>

The intent of commit 646013f513f3 ("dma-buf: enable DMABUF_DEBUG by default
on DEBUG kernels") is clear, but it mixes up the config option name. The
config option for kernel debugging is named DEBUG_KERNEL, not DEBUG.

Fix up the DMABUF_DEBUG definition to use the intended name.

Fixes: 646013f513f3 ("dma-buf: enable DMABUF_DEBUG by default on DEBUG kernels")
