Use DEBUG_KERNEL, the Kconfig symbol for a debug kernel. Fixes: 646013f513f3 ("dma-buf: enable DMABUF_DEBUG by default on DEBUG kernels") Assisted-by: LLM Signed-off-by: Karl Mehltretter --- This enables the dma-buf debug checks on every CONFIG_DEBUG_KERNEL configuration, which is what 646013f513f3 set out to do. If that is too broad today, the alternative is to restore the previous "default y if DMA_API_DEBUG". drivers/dma-buf/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/dma-buf/Kconfig b/drivers/dma-buf/Kconfig index 7efc0f0d0712..e4f078a326a4 100644 --- a/drivers/dma-buf/Kconfig +++ b/drivers/dma-buf/Kconfig @@ -43,7 +43,7 @@ config UDMABUF config DMABUF_DEBUG bool "DMA-BUF debug checks" depends on DMA_SHARED_BUFFER - default y if DEBUG + default y if DEBUG_KERNEL help This option enables additional checks for DMA-BUF importers and exporters.
