kconfig: Change the format of KERNELVERSION
Change the format of KERNELVERSION as it exists in Kconfig to match it's format elsewhere. Specifically, change from a string format "1.10.3" to a numerical format. This format change is a backwards-incompatible change. Any out-of-tree Kconfig sources that were accessing KERNELVERSION with $(KERNELVERSION) will need to be ported. This change is to fix a bug. KERNELVERSION should have always been in a numerical format. It should have been in a numerical format because; KERNELVERSION is in a numerical format as a CMake variable and as a C macro. The purpose of having KERNELVERSION available in Kconfig is to have configuration depend on the version, but this is only possible if it exists in a numerical format[0]. [0] A string comparison of two semver strings does not always result in a correct version comparison. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>
