Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fixes from Thomas Gleixner:
"A few small fixes for timer drivers:
- Prevent infinite recursion in the arm architected timer driver with
ftrace
- Propagate error codes to the caller in case of failure in EM STI
driver
- Adjust a bogus loop iteration in the arm architected timer driver
- Add a missing Kconfig dependency to the pistachio clocksource to
prevent build failures
- Correctly check for IS_ERR() instead of NULL in the shared timer-of
code"
