| |
Hi,
Sparse reports the following:
CHECK drivers/staging/rtl8188eu/core/rtw_mlme.c drivers/staging/rtl8188eu/core/rtw_mlme.c:1003:9: warning: context imbalance in 'rtw_free_assoc_resources' - different lock contexts for basic block
The code in question is as follows:
if (lock_scanned_queue) spin_lock_bh(&(pmlmepriv->scanned_queue.lock));
pwlan = rtw_find_network(&pmlmepriv->scanned_queue, tgt_network->network.MacAddress);
if (lock_scanned_queue) spin_unlock_bh(&(pmlmepriv->scanned_queue.lock));
As this fragment uses the identical test to unlock that is used to lock, and the test variable is not touched, I think this is a false indication. I am using version 0.4.4 of sparse.
Thanks,
Larry
