X-Git-Url: http://git.openwrt.org/%22https:/collectd.org//%22/%22https:/collectd.org/%22?a=commitdiff_plain;h=126cb4f54ae2e5956052e54aff8da28f9ca26601;p=project%2Fbcm63xx%2Fatf.git

rcar_gen3: drivers: qos: M3N: Drop MD pin check

The DBSC_SCFCTST2 is always written with the same value, no matter
what the MD pin value is, drop the entire check and just write the
register with the one and only possible value.
