Subject: [PATCH 5.14 045/100] dma-buf: DMABUF_DEBUG should depend on DMA_SHARED_BUFFER

From: Geert Uytterhoeven <geert@...ux-m68k.org>

[ Upstream commit cca62758ebdd71fcfb6d589d6487a7f26398d50d ]

DMA-BUF debug checks are an option of DMA-BUF.  Enabling DMABUF_DEBUG
without DMA_SHARED_BUFFER does not have any impact, as drivers/dma-buf/
is not entered during the build when DMA_SHARED_BUFFER is disabled.

Fixes: 84335675f2223cbd ("dma-buf: Add debug option")
