| |
Sparse reports several warnings; warning: context imbalance in lock_hrtimer_base() - wrong count at exit warning: context imbalance in hrtimer_start_range_ns() - unexpected unlock warning: context imbalance in hrtimer_try_to_cancel() - unexpected unlock warning: context imbalance in __hrtimer_get_remaining() - unexpected unlock
The root cause is a missing annotation of lock_hrtimer_base() which causes also the "unexpected unlock" warnings.
Add the missing __acquires(timer->base) annotation
