SubjectRe: [PATCH v2 18/20] extcon: intel-cht-wc: Refactor cht_wc_extcon_get_charger()
From
Date
Hello,

I think that you need to squash it with patch21
I'm not sure that this patch is either atomic or not because
you remove the 'return EXTCON_CHG_USB_SDP/EXTCON_CHG_USB_SDP'
without explaining why it is no problem. Just mention that
pass the role to next 'switch' cases. But, before this change,
there were any reason to return the type of charger cable
before switch statement.

According to your patch description, you don't need
to make the separate patch of it. Please squash it with patch21.
