uv_time: add parameter to uv_read_rtc()
uv_read_rtc() is referenced by read member of struct clocksource clocksource_uv. In include/linux/clocksource.h, read of struct clocksource is declared as: cycle_t (*read)(struct clocksource *cs) This got introduced recently in: 8e19608: clocksource: pass clocksource to read() callback But arch/x86/kernel/uv_time.c was not properly converted by that pach. This patch adds a dummy parameter (struct clocksource type) to uv_read_rtc() to fix the incompatible reference in clocksource_uv, and add a NULL parameter in all places where uv_read_rtc() gets called.
