Commit dfc256dac54c ("calibrate: Rework delay timer calibration")
renamed read_current_timer() to delay_read_timer() and inverted its
return convention: the old function returned 0 on success, the new one
returns true on success. The ternary in get_cycles() was not updated,
so it now evaluates to 0 whenever the delay timer is present and
readable, which is precisely when it used to work.commit e1e3a0ab69c64eedaf53dce9306f8a090bf038f0 upstream
