Subject: [PATCH 1/1] ufs: scsi: fix sparse errors in ufshcd_system_suspend
Date: Sun, 5 Oct 2014 17:10:07 +0300 [thread overview]
Message-ID: <1412518207-27135-1-git-send-email-draviv@codeaurora.org> (raw)
This patch fixes newly introduced sparse warning in
ufshcd_system_suspend, introduced by UFS power management series.
Sparse warning:
drivers/scsi/ufs/ufshcd.c:5118 ufshcd_system_suspend()
error: we previously assumed 'hba' could be null (see line 5089)
To fix it, we return 0 in case HBA is not initialized or is
not powered.
