Subject: rtc-at91rm9200: add match-table compile guard
The members of Atmel's at91sam9x5 family (9x5) have a broken RTC interrupt
mask register (AT91_RTC_IMR). It does not reflect enabled interrupts but
instead always returns zero.
The kernel's rtc-at91rm9200 driver handles the RTC for the 9x5 family.
Currently when the date/time is set, an interrupt is generated and this
driver neglects to handle the interrupt. The kernel complains about the
un-handled interrupt and disables it henceforth. This not only breaks the
RTC function, but since that interrupt is shared (Atmel's SYS interrupt)
then other things break as well (e.g. the debug port no longer accepts
characters).
Tested on the at91sam9g25. Bug confirmed by Atmel.
This patch (of 5):
Add missing match-table compile guard.
