Hi,
Would you please provide before and after examples?

I use xconfig quite a lot and it already shows me, e.g., for
CONFIG_DRM:


Symbol: DRM [=y]
Type : tristate
Prompt: Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)
Defined at drivers/gpu/drm/Kconfig:7
Depends on: HAS_IOMEM [=y] && (AGP [=y] || AGP [=y]=n) && !EMULATED_CMPXCHG && MMU [=y]
Location:
-> Device Drivers
-> Graphics support
Selects: I2C [=y] && I2C_ALGOBIT [=y] && DMA_SHARED_BUFFER [=y]




so what and where does this patch add debug info?

Thanks.
