While there are some *.dts files in the kernel source tree, that is no
guarantee that:

a) People don't have custom *.dts files that are not in the kernel
source tree, and hence can't be updated by Linux kernel patches.

b) People actually replace their *.dtb when updating their zImage. Since
DT is explicitly supposed to be an ABI, everything is explicitly
supposed to work if they do only update their zImage and not their *.dtb.
