linux-next: build failure after merge of the xen-tip tree

[Stephen Rothwell]

Hi all,

After merging the xen-tip tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/base/power/trace.c: In function 'generate_pm_trace':
drivers/base/power/trace.c:170:10: error: 'return' with a value, in function returning void [-Werror=return-type]
  170 |   return 0;
      |          ^
drivers/base/power/trace.c:163:6: note: declared here
  163 | void generate_pm_trace(const void *tracedata, unsigned int user)
      |      ^~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Caused by commit

  38b6c7137e13 ("PM: base: power: don't try to use non-existing RTC for storing data")

I used the xen-tip tree from next-20210914 for today.
