Hello Dave Gordon,
This is a semi-automatic email about new static checker warnings.
The patch fce91f22ff31: "drm/i915/guc: add enable_guc_loading
parameter" from May 20, 2016, leads to the following Smatch complaint:
drivers/gpu/drm/i915/intel_guc_loader.c:418 intel_guc_setup()
error: we previously assumed 'fw_path' could be null (see line 417)
drivers/gpu/drm/i915/intel_guc_loader.c
416 goto fail;
417 } else if (fw_path == NULL || *fw_path == '\0') {
^^^^^^^^^^^^^^^
New check.
418 if (*fw_path == '\0')
^^^^^^^^^^^^^^^
Oops.
419 DRM_INFO("No GuC firmware known for this platform\n");
420 err = -ENODEV;
regards,
dan carpenter
