Subject: Re: [PATCH] drivers/crypto/Kconfig: Let 'DEV_QCE' depend on both
 HAS_DMA and HAS_IOMEM

Oh, sorry, this patch can still be alive, after a long discussion, we
need keep current status no touch -- still let individual modules to
depends on HAS_IOMEM and/or HAS_DMA, if they need them.

So please help check the patch, when you have time.

Thanks.
