* The core I2C code now iterates over the driver model's list instead
of the i2c-internal one in some places where it's safe:
- Passing a command/ioctl to each client, a mechanims
used almost exclusively by DVB adapters;
- Device address checking, in both i2c-core and i2c-dev.
* Provide i2c_verify_client() to use with driver model iterators.
* Flag the relevant i2c_adapter and i2c_client fields as deprecated,
to help prevent new users from appearing.
For the moment the list needs to stick around, since some issues show
up when deleting devices created by legacy I2C drivers. (They don't

ide: fix final status check in drive_cmd_intr()
Don't check for READY_STAT bit being set for PIO-in protocol (makes the
final status check in drive_cmd_intr() match the one in task_in_intr()).
Also fix function name reported by ide_error() call while at it.
