Tabs to indent, spaces to align. Spaces here please.

modules.bbclass already sets KERNEL_PATH and KERNEL_SRC, perhaps you
could use one of those?
If you just use ${includedir} in your install I believe you can skip
PREFIX here and get the /usr part right there.

Current kernels recommend using M= instead of SUBDIRS=:
SRC := $(shell pwd)
make -C $(KERNEL_SRC) M=$(SRC) modules_install
See the hello-mod example in meta-skeleton/recipes-kernel/hello-mod for
a minimal example.

Use ${includedir} here
