  From: kyrie wu <kyrie.wu@mediatek.com>

some chips have multi-hw, but others have only one,
modify the condition of multi-hw judgement

Fixes: 934e8bccac95 ("mtk-jpegenc: support jpegenc multi-hardware")

So presumably the mtk8195 is multi core and the other variants are single core, but...

...this has value 0, so multi core is the default. This means that all variants are
seen as multi core.

I think this is a poorly chosen name: wouldn't it be better
to just make this a 'bool multi_core;'?

In any case, this patch doesn't look right.

Dear Hans,

Thanks for your reminding, I will fix this problem.

Thanks, I would change the choosing.
