Subject: net: macb: drop usrio pointer on EyeQ5 config
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cd1082a96f9a1ffe053e48ac0a1b4fffb189c30e;p=thirdparty%2Fkernel%2Flinux.git

net: macb: drop usrio pointer on EyeQ5 config

USRIO is disabled on this platform, drop its inherited usrio config.
We will end up with MACB_CAPS_USRIO_DISABLED on this platform:
 - We have no config->usrio so macb_configure_caps() deduces that the
   feature is disabled.
 - Anecdotally, we would also land in the runtime detection codepath
   that reads DCFG1.
