Hi Linus,

It caused a few build regressions:

- missing include of errno.h
- clksrc_dbx500_prcmu_init stub needs to be static inline, or it causes a
  link failure.
- clksrc_dbx500_timer_base may be initialized when it's not actually linked in

For the last one, I think it would actually be best to make the timer 
a platform_device and pass the address in platform_data or device tree
property, or alternatively make it an argument to clksrc_dbx500_prcmu_init
and make the variable static.

Please send a new pull request with these things fixed, either with
patches on top or replacing the original ones, whichever you prefer.
