Hi Michal,

Thanks for the reviews!

Not really. The rule would have matched if there was just "something"
inbetween. It did not match because the "something" involves the
variable 'pdev', so we can't remove it. And just changing towards
'dev_get_drvdata' and keeping 'pdev' was not worth the hazzle in my
book. Especially since I think the code should probably get refactored.
Calling platform_get_irq() in suspend/resume paths in order to get the
irq_data looks a little expensive to me, but I haven't tested it.

Best wishes,

   Wolfram

PS: Please quote only relevant parts of the message, it is a lot easier
to find comments then IMO.
