x86/platform/olpc: Do not call of_platform_bus_probe()

robherring · suryasaimadhu · commit c04e55388a4f · 2018-11-17T19:29:55.000+01:00
The DT core will probe the DT by default now, so the OLPC platform code calling of_platform_bus_probe() is not necessary. The algorithm for what nodes are probed is a little different in how compatible is handled, but since OLPC uses compatible strings for matching it is not affected by this difference. Also, only the battery node located at the root level gets a device created as the dcon is a PCI device and the RTC device is created in olpc-xo1-rtc.c.
