Re: [PATCH 2/3] checkpatch: kconfig: check help texts for menuconfig and choice

for the last symbol in a file. Perhaps, EOF could be also an ending of symbol definition. This patch is a good improvement enough, so I queued it up. If you have an idea for further improvement, v2 is welcome, of course. -- Best Regards Masahiro Yamada

Re: [PATCH 3/3] checkpatch: kconfig: prefer 'help' over '---help---'

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. -- Best Regards Masahiro Yamada

Some people use .PRECIOUS to suppress file removal, but it is wrong IMO. .SECONDARY is the right one, but one problem is, this does not work with pattern rules.
