[PATCH 1/3] ASoC: Intel: Skylake: fix pointer scaling

[PATCH 1/3] ASoC: Intel: Skylake: fix pointer scaling

[Vinod Koul]

From: Alan <gnomes@lxorguk.ukuu.org.uk>

skl_tplg_tlv_control_set does pointer maths on data but forgets that data
is not uint8_t so the maths is already scaled in the pointer type.

[PATCH 2/3] ASoC: Intel: Skylake: remove bogus comparison of an array with NULL

[Vinod Koul]

From: Alan <gnomes@lxorguk.ukuu.org.uk>

dfw_ac->params is an array not a pointer. It will never be NULL. The check
on ac->max appears sufficient.

Please ensure that the name and signoff match up.  I'm fairly sure that
both are for the same person here but it's not something I should have
to think about and it is important to ensure that we have signoffs for
everything.

Well, I already applied this one anyway since it was a fix (though I did
