Subject: linux-next: build failure after merge of the rtc tree

Hi all,

After merging the rtc tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/rtc/rtc-at91rm9200.c:561:13: error: 'at91_rtc_remove' defined but not used [-Werror=unused-function]
  561 | static void at91_rtc_remove(struct platform_device *pdev)
      |             ^~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Caused by commit

  48bc8830fbed ("rtc: at91rm9200: Convert to platform remove callback returning void")

This function lost its __exit attribute (which includes a "used"
attribute) and exit_p(x) is NULL when not being built with
CONFIG_MODULE set.  This build has CONFIG_RTC_DRV_AT91RM9200=y

I have reverted that commit for today.

Stephen Rothwell
