Maybe it's just me, because on my config I have CONFIG_DEBUG_FS=y, and on the system I was testing usbatm I had CONFIG_DEBUG_FS=n. BTW, on x86_64 to disable CONFIG_DEBUG_FS you need to disable CONFIG_AMD_IOMMU_STATS, which is enabled by default in the x86_64_defconfig (I think that CONFIG_AMD_IOMMU_STATS=n it's a better default). If you enable CONFIG_DEBUG_KERNEL you need to disable CONFIG_FTRACE which is enabled by default. So a lot of users will have CONFIG_DEBUG_FS already selected.
