This is quite clear from the patch itself.  What is unclear is "why". 
Does it fix a build error?  If so, please describe and add a Fixes: if
appropriate.  Is it just a cleanup?  etcetera.

Thanks.

Hi, Kefeng,

Thanks for the patch, looks good to me, but as Andrew commented,
please add some info about the motivation in the commit log.

With the update,

oh, it's just a cleanup, I think it is no need to use the word 'correct',
will update the subject and change log.

It's more clear and simple to just use IS_ENABLED(CONFIG_HWPOISON_INJECT)
to check whether or not to enable HWPoison injector module instead of
CONFIG_HWPOISON_INJECT/CONFIG_HWPOISON_INJECT_MODULE.
