[PATCH] checkpatch: add judgment condition for Kconfig help test

[PATCH] checkpatch: add judgment condition for Kconfig help test

[Cixi Geng]

From: Cixi Geng <cixi.geng1@unisoc.com>

The has_help only counted the  situation which the patch file add
a help line, when the config was renamed and  modify description,
the has_help is zero for the "help" line not added.

here is one case:
    the modify file: drivers/iio/adc/Kconfig  line(1047)

    -config SC27XX_ADC
    +config SPRD_ADC
     	tristate "Spreadtrum SC27xx series PMICs ADC"
     	depends on MFD_SC27XX_PMIC || COMPILE_TEST
    +	depends on ARCH_SPRD
     	help
    -	  Say yes here to build support for the integrated ADC inside the
    -	  Spreadtrum SC27xx series PMICs.
    +	  Say yes here to build support for the integrated ADC inside of the
    +	  Spreadtrum SC27xx and UMPxx series PMICs.

     	  This driver can also be built as a module. If so, the module
     	  will be called sc27xx_adc.

the checkpatch result:
    WARNING: please write a help paragraph that fully describes the config symbol
    #23: FILE: drivers/iio/adc/Kconfig:1050:
    +config SPRD_ADC
    +	tristate "Spreadtrum's ADC PMICs driver"
     	depends on MFD_SC27XX_PMIC || COMPILE_TEST
    +	depends on ARCH_SPRD
     	help

Is the indentation correct in each line? No TABs/spaces mix?

OK, I made those changes to that Kconfig file and ran checkpatch.
I didn't get any of the following checkpatch results.

Are you using a current version of checkpatch?

yes, I'am sure there is some wrong result about the patch, My local
verion is based on (7475e51b8796 (HEAD -> local, origin/master,
origin/HEAD) Merge tag 'net-6.7-rc2' of
git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net)

my steps is modify the Kconfig, generate a test commit. and git format
this commit, then run ./scripts/checkpatch.pl 0001-test.patch.
