Instead of using to_pci_dev + pci_get_drvdata,
use dev_get_drvdata to make code simpler.

Thanks for your patch.
I think using pci_get_drvdata() here mainly make a pair with the pci_set_drvdata() in probe.

Thanks for your reply.
I will change pci_set_drvdata() to dev_set_drvdata() in the next
version to keep their consistency.

wrappers around the dev_*() equivalents; you can use the one you like at
any given occasion. In this case the pci prefixed one is more convenient.
