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 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.

Looks like this interface has just been changed, by commit 8e19608e8b5c001e4a66ce482edc474f05fb7355.

This looks OK to me.

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.

[ Impact: cleanup, address compiler warning ]
