Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle: "Two more MIPS fixes for 4.9: - RTC: Return -ENODEV so an external RTC will be tried - Fix mask of GPE frequency These two have been tested on Imagination's automated test system and also both received positive reviews on the linux-mips mailing list" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Lantiq: Fix mask of GPE frequency MIPS: Return -ENODEV from weak implementation of rtc_mips_set_time
