Subject: [PATCH Broadcom/stblinux] soc: brcmstb: add stubs for getting platform IDs
From: Rafał Miłecki <rafal@...ecki.pl>
Some brcmstb drivers may be shared with other SoC families. E.g. the
same USB PHY block is shared by brcmstb and BCM4908.
To avoid building brcmstb common code on non-brcmstb platforms we need
stubs for:
1. brcmstb_get_family_id()
2. brcmstb_get_product_id()
(to avoid "undefined reference to" errors).
With this change PHY_BRCM_USB will not have to unconditionally select
SOC_BRCMSTB anymore.
