Author: jhibbits Date: Thu Aug 30 23:54:49 2012 New Revision: 239929 URL: http://svn.freebsd.org/changeset/base/239929 Log: MFC r239548: phandle_t is unsigned, and OF_finddevice() returns (phandle_t)(-1) on failure, so check for that instead of 0. While here, provide a better description for ATI backlight driver.
