Fix hpet_(un)register_irq_handler() for emulation
Fix hpet_(un)register_irq_handler() for when CONFIG_HPET_EMULATE_RTC=n. They are provided macros that substitute value 0, but if they are called as functions and the return value isn't checked, the following warnings appear: drivers/char/rtc.c: In function `rtc_init': drivers/char/rtc.c:1063: warning: statement with no effect drivers/char/rtc.c: In function `rtc_exit': drivers/char/rtc.c:1157: warning: statement with no effect Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
