Since platform_register_driver() was converted to set the .owner of a driver, there was a codepath on which the owner would have been erased. This series fixes that and adds a warning to prevent such cases go unnoticed in the future. For consistency, a semantic patch is also added which reports when .owner gets unnecissarily set. More details in the patch descriptions. Thanks go to Russell King for pointing out this problem and to Julia Lawall for help with the semantic patch.
All these patches have been tested on a custom board. This resend was rebased to rc2. It produced identical patches. IMO this should go into v3.18 since it is a bugfix. Please apply. The cleanup series for removing .owner in the kernel tree will be resend later, too, as a seperate pull request.
