As has been stated several times, this form of the subject is incorrect. It 
should be: "rtlwifi: <driver_name>: <subject>

I would prefer that there be separate patches for each driver, not that the 
changes be lumped into a single patch as was done here. Such organization makes 
it a lot easier to find the patches for a given driver in case something goes 
wrong.Note: The driver for ps is rtl_pci, and that for rtl8192c is 
rtl8192c-common. The other driver names match their directory.
