[alexandre . belloni]

From: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxx>

rx6110_spi_of_match is not used when !OF, leading to a warning:

>> drivers/rtc/rtc-rx6110.c:384:34: warning: 'rx6110_spi_of_match' defined but not used [-Wunused-const-variable=]
     384 | static const struct of_device_id rx6110_spi_of_match[] = {
         |                                  ^~~~~~~~~~~~~~~~~~~
