Sparse reports warnings at wakeup_sources_read_lock() and wakeup_sources_read_unlock() warning: context imbalance in wakeup_sources_read_lock() - wrong count at exit context imbalance in wakeup_sources_read_unlock() - unexpected unlock The root cause is the missing annotation at wakeup_sources_read_lock() and wakeup_sources_read_unlock() Add the missing __acquires(&wakeup_srcu) annotation Add the missing __releases(&wakeup_srcu) annotation Signed-off-by: Jules Irenge <jbi.octave@gmail.com> --- drivers/base/power/wakeup.c | 2 ++ 1 file changed, 2 insertions(+)
