RTC incompatible pointer请问大佬们在哪部分改比较适合

编译ART-Pi RTC 时 遇到

arm-none-eabi-gcc "../libraries/drivers/drv_usart.c"
../libraries/drivers/drv_rtc.c:278:5: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
stm32_rtc_get_secs,
../libraries/drivers/drv_rtc.c:278:5: note: (near initialization for 'stm32_rtc_ops.get_secs')
../libraries/drivers/drv_rtc.c:279:5: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
stm32_rtc_set_secs,
^
../libraries/drivers/drv_rtc.c:279:5: note: (near initialization for 'stm32_rtc_ops.set_secs')
../libraries/drivers/drv_rtc.c:282:5: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
stm32_rtc_get_timeval,
^
../libraries/drivers/drv_rtc.c:282:5: note: (near initialization for 'stm32_rtc_ops.get_timeval')

程序可以正常运行，但是不是很舒服。大佬们觉得， 在那部分改，比较适合？
