Subject: [PATCH v1] scsi: ufs: fix arguments order some trace calls
Date: Tue, 10 Jan 2017 16:48:25 -0800 [thread overview]
Message-ID: <1484095705-3962-1-git-send-email-subhashj@codeaurora.org> (raw)
Colin Ian King <colin.king@canonical.com> reported that with
commit 7ff5ab473633 ("scsi: ufs: add tracing support") static analysis
is reporting that we may have swapped arguments on calls to:
trace_ufshcd_runtime_resume,
trace_ufshcd_runtime_suspend,
trace_ufshcd_system_suspend,
trace_ufshcd_system_resume,
and trace_ufshcd_init
Where:
hba->uic_link_state is passed to dev_state
hba->curr_dev_pwr_mode is passed to link_state
This wasn't intentional so it's a bug. This change fixed this bug.
