Nasser, All,
On 2018-11-14 10:41 +0330, Nasser Afshin spake thusly:
> This patch allows us to define config prefix with CONFIG_ environment
> variable.
>
> By setting the proper config prefix, we will have proper 'redundant
> configuration warnings' when we use '-r -m' options.
>
> This is actually already in mainline for v4.20-rc1:
> 2cd3faf87d2d8f6123adf34741b9a7b98828a76f
> ("merge_config.sh: Allow to define config prefix")
