mac_find_mode is EXPORT_SYMBOL() and marked __init
This does not look correct to me. How do we know that it is valid to use
this exported symbol?
Fix: do not mark mac_find_mode() as __init?

As indicated a rename would do the trick.
s/megaraid_pci_driver_g/megaraid_pci_driver/g
The _g syntax does not look common and for this case we will not soften
up the pattern to look for "driver" anywhere in the variable.

Agree.
s/\<tpm_inf_pnp\>/tpm_inf_driver/g

Look sane. The naming *_interface looks generic - so maybe we should
whitelist it too?

grepping shows up that naming *_drv is quite common.
So the better fix would probarly be to whitelist it too?
