Title
thermal/drivers/rcar: Fix error checking in probe()
Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal/drivers/rcar: Fix error checking in probe()
This code accidentally calls thermal_zone_device_enable() before checking
whether thermal_zone_device_register_with_trips() failed. Move the call
until later to avoid an error pointer dereference of "priv->zone".
The driver works differently depending on if we are using OF thermal or
not. We use thermal_add_hwmon_sysfs() if we are using OF thermal and
call thermal_zone_device_enable() if not. We can share same error check
for if either of these fail.
Moving the thermal_zone_device_enable() call is a bit cleaner as well.
The original code used a three step process to cleanup:
1. Call thermal_zone_device_unregister() to cleanup.
2. Set priv->zone to an error pointer to preserve the error code.
3. Set priv->zone to NULL to avoid a second call to
thermal_zone_device_unregister() in the rcar_thermal_remove()
function.
Now we can just do a direct goto error_unregister and rcar_thermal_remove()
handles the cleanup properly.
