I applied this, but perhaps the line number for the offending part
could be improved.
The warning looks like this.
WARNING: prefer 'help' over '---help---' for new help texts
#1109: FILE: init/Kconfig:1109:
+config SGETMASK_SYSCALL
The #1109 points to the line of the symbol start.
IMHO, it is even better to point to the '---help---' line.
