Subject: [PATCH 5/5] ipmi: Add missing annotation for ipmi_ssif_lock_cond() and ipmi_ssif_unlock_cond()
Date: Fri, 3 Apr 2020 17:05:05 +0100 [thread overview]
Message-ID: <20200403160505.2832-6-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200403160505.2832-1-jbi.octave@gmail.com>
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)
