Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/gma500: Fix null dereference in hdmi teardown<br />
<br />
pci_set_drvdata sets the value of pdev->driver_data to NULL,<br />
after which the driver_data obtained from the same dev is<br />
dereferenced in oaktrail_hdmi_i2c_exit, and the i2c_dev is<br />
extracted from it. To prevent this, swap these calls.<br />
