Since we moved the drivers debugfs directory under ieee80211 debugfs the debugfs entries need to be added after wiphy_register() has been called. For most part that has been done accordingly, but for the debugfs entries added by SDIO it was not and failed silently. This patch fixes that by adding a bus-layer callback for it.
