Subject: Re: [PATCH v3 1/1] spi: offload: Add offset parameter

Hi Jonathan,

Yes, current ad4030 series depends on this.
Though, since this updates the SPI subsystem, I separated it from ad4030 set.
I missed that aspect of the devel process. If we need an immutable branch to
make this split series for ad4030 work, then yes, please, I'd like an 
immutable branch with this patch.
