Subject: tc86c001: remove ->init_chipset method
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b16040b14e766d390138b04c8829c816f4c1d95b;p=openwrt%2Fstaging%2Fblogic.git

tc86c001: remove ->init_chipset method

* Reserve PCI BAR 5 in tc86c001_init_one() and remove no longer needed
  init_chipset_tc86c001().

While at it:

* Add & use DRV_NAME define.
