Arnd Bergmann e698a51239 drivers/rtc/rtc-pcf8563.c: fix uninitialized use warning 
gcc-4.9 found a potential condition under which the 'pending' variable
may be used uninitialized:

  drivers/rtc/rtc-pcf8563.c: In function 'pcf8563_irq':
  drivers/rtc/rtc-pcf8563.c:173:5: warning: 'pending' may be used uninitialized in this function [-Wmaybe-uninitialized]

This is because in the pcf8563_get_alarm_mode() function, we check any
nonzero return of pcf8563_read_block_data, but in the irq function we
only check for negative values, so a possible positive value does not
get detected if the compiler chooses not to inline the entire call
chain.

Checking for any non-zero value in the interrupt handler as well is just
as correct and lets the compiler know what we are doing, without needing
a bogus initialization.
