Subject: [PATCH 5.10 119/157] usb: typec: Remove vdo[3] part of tps6598x_rx_identity_reg struct

From: Elias Rudberg <mail@...asrudberg.se>

commit 3cac9104bea41099cf622091f0c0538bcb19050d upstream.

Remove the unused "u32 vdo[3]" part in the tps6598x_rx_identity_reg
struct. This helps avoid "failed to register partner" errors which
happen when tps6598x_read_partner_identity() fails because the
amount of data read is 12 bytes smaller than the struct size.
Note that vdo[3] is already in usb_pd_identity and hence
shouldn't be added to tps6598x_rx_identity_reg as well.

Fixes: f6c56ca91b92 ("usb: typec: Add the Product Type VDOs to struct usb_pd_identity")
