2013-04-15i2c-designware-pci: use managed functions pcim_* and devm_*Andy Shevchenko1-51/+17
This makes the error handling much more simpler than open-coding everything and in addition makes the probe function smaller an tidier.

2013-04-15i2c-designware-pci: use dev_err() instead of printk()Andy Shevchenko1-2/+2
With dev_err() we can get the device instance printed as well and is pretty much standard to use dev_* macros in the drivers anyway. In addition correct the indentation of probe() arguments.

2013-02-22i2c: Remove unneeded xxx_set_drvdata(..., NULL) callsDoug Anderson1-2/+0
There is simply no reason to be manually setting the private driver data to NULL in the remove/fail to probe cases. This is just extra cruft code that can be removed. A few notes: * Nothing relies on drvdata being set to NULL. * The __device_release_driver() function eventually calls dev_set_drvdata(dev, NULL) anyway, so there's no need to do it twice. * I verified that there were no cases where xxx_get_drvdata() was being called in these drivers and checking for / relying on the NULL return value. This could be cleaned up kernel-wide but for now just take the baby step and remove from the i2c subsystem.

2012-12-22i2c: remove __dev* attributes from subsystemBill Pemberton1-3/+3
CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit.

Convert static struct pci_device_id *[] to static DEFINE_PCI_DEVICE_TABLE tables. Use DEFINE_PCI_DEVICE_TABLE ensures we make the pci_device_id table const and marked as __devinitconst.

2011-10-29i2c-designware: Fix PCI core warning on suspend/resumeOctavian Purdila1-21/+8
PCI core warns if the legacy PM and new PM functions are present. Update the driver to only use the new power management framework.
