621bae79f1 drivers/rtc/rtc-tegra.c: clean up probe/remove routines 
Use the devres managed resource functions in the probe routine.  Also
affects the remove routine where the previously used free and release
functions are not needed.

The devm_* functions eliminate the need for manual resource releasing and
simplify error handling.  Resources allocated by devm_* are freed
automatically on driver detach.

e57ee01750 drivers/rtc/rtc-tegra.c: properly initialize spinlock 
Using __SPIN_LOCK_UNLOCKED for a dynamically allocated lock is wrong and
breaks the build with PREEMPT_RT_FULL.
