firewire: core: prefix log messages with card name
Associate all log messages from firewire-core with the respective card because some people have more than one card. E.g. firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0 firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0 firewire_core: created device fw0: GUID 0814438400000389, S800 firewire_core: phy config: new root=ffc1, gap_count=5 firewire_core: created device fw1: GUID 0814438400000388, S800 firewire_core: created device fw2: GUID 0001d202e06800d1, S800 turns into firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0 firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0 firewire_core 0000:04:00.0: created device fw0: GUID 0814438400000389, S800 firewire_core 0000:04:00.0: phy config: new root=ffc1, gap_count=5 firewire_core 0000:05:00.0: created device fw1: GUID 0814438400000388, S800 firewire_core 0000:04:00.0: created device fw2: GUID 0001d202e06800d1, S800 This increases the module size slightly; to keep this in check, turn the former printk wrapper macros into functions. Their implementation is largely copied from driver core's dev_printk counterparts. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
