Subject: [bug report] drm/i915/gvt: replace the gvt_err with gvt_vgpu_err
Date: Wed, 22 Mar 2017 14:24:02 +0300 [thread overview]
Message-ID: <20170322112402.GA17653@mwanda> (raw)
Hello Tina Zhang,
This is a semi-automatic email about new static checker warnings.
The patch 695fbc08d80f: "drm/i915/gvt: replace the gvt_err with
gvt_vgpu_err" from Mar 10, 2017, leads to the following Smatch
complaint:
drivers/gpu/drm/i915/gvt/kvmgt.c:1344 kvmgt_guest_exit()
warn: variable dereferenced before check 'info' (see line 1342)
drivers/gpu/drm/i915/gvt/kvmgt.c
1341 {
1342 struct intel_vgpu *vgpu = info->vgpu;
^^^^^^^^^^
Patch adds a new dereference.
1343
1344 if (!info) {
^^^^^
Existing check.
1345 gvt_vgpu_err("kvmgt_guest_info invalid\n");
1346 return false;
regards,
dan carpenter
