Hello Dolev Raviv,
This is a semi-automatic email about new static checker warnings.
The patch e785060ea3a1: "ufs: definitions for phy interface" from Sep
25, 2014, leads to the following Smatch complaint:
drivers/scsi/ufs/ufshcd.c:5118 ufshcd_system_suspend()
error: we previously assumed 'hba' could be null (see line 5089)
drivers/scsi/ufs/ufshcd.c
5088
5089 if (!hba || !hba->is_powered)
^^^^
Existing check for NULL.
5090 goto out;
5091
[ snip ]
5115 ret = ufshcd_suspend(hba, UFS_SYSTEM_PM);
5116 out:
5117 if (!ret)
5118 hba->is_sys_suspended = true;
^^^^^^^^^^^^^^^^^^^^^
New unchecked dereference. This is a One Err Bug caused by "out" label
style error handling.
5119 return ret;
5120 }
regards,
dan carpenter
