Hi all,

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

drivers/staging/android/vsoc.c: In function 'handle_vsoc_cond_wait':
drivers/staging/android/vsoc.c:440:33: error: passing argument 1 of 'hrtimer_init_sleeper_on_stack' from incompatible pointer type [-Werror=incompatible-pointer-types]

                                 ^~~

                 from drivers/staging/android/vsoc.c:19:

                                           ~~~~~~~~~~~~~~~~~~~~~~~~^~

Caused by commit

  82e18bace3dd ("hrtimer: Consolidate hrtimer_init() + hrtimer_init_sleeper() calls")

I have added the following patch for today:
