Subject[PATCH 5/5] ipmi: Add missing annotation for ipmi_ssif_lock_cond() and ipmi_ssif_unlock_cond()
Date
Sparse reports a warning at ipmi_ssif_unlock_cond()
and ipmi_ssif_lock_cond()

warning: context imbalance in ipmi_ssif_lock_cond()
- wrong count at exit
warning: context imbalance in ipmi_ssif_unlock_cond()
- unexpected unlock

The root cause is the missing annotation at ipmi_ssif_unlock_cond()
and ipmi_ssif_lock_cond()

Add the missing __acquires(&ata_scsi_rbuf_lock)
Add the missing __releases(&ata_scsi_rbuf_lock)
