Hello Mario Limonciello,
This is a semi-automatic email about new static checker warnings.
The patch d17a5ee12973: "Add WMI driver for controlling AlienFX
features on some Alienware products" from Apr 4, 2014, leads to the
following Smatch complaint:
drivers/platform/x86/alienware-wmi.c:551 alienware_wmi_exit()
warn: variable dereferenced before check 'platform_device' (see line 549)
drivers/platform/x86/alienware-wmi.c
548 {
549 alienware_zone_exit(platform_device);
^^^^^^^^^^^^^^^
550 remove_hdmi(platform_device);
^^^^^^^^^^^^^^^
551 if (platform_device) {
^^^^^^^^^^^^^^^
552 platform_device_unregister(platform_device);
553 platform_driver_unregister(&platform_driver);
