2009-05-15[SCSI] ses: fix problems caused by empty SES provided nameYinghai Lu
We use the name provided by SES to name objects. An empty name is legal in SES but causes problems in our generic device hierarchy. Fix this by falling back to a number if the name is either NULL or empty. Also fix a secondary bug spotted in that dev_set_name(dev, name) uses a string format and so would go wrong if name contained a '%'.

2009-04-02memory_accessor: implement the new memory_accessor interface for I2C EEPROMKevin Hilman
In the case of at24, the platform code registers a 'setup' callback with the at24_platform_data. When the at24 driver detects an EEPROM, it fills out the read and write functions of the memory_accessor and calls the setup callback passing the memory_accessor struct. The platform code can then use the read/write functions in the memory_accessor struct for reading and writing the EEPROM.

Change hpilo open and close logic to spin for 10usec between checking device, rather than every usec. Because the loop is coded to take up to 10ms, it seemed prudent to increase the interval between polling the device, to reduce the load on the system and allow more other work to happen.

2009-02-05hpilo: open/close fixDavid Altobelli
The device can take a while to respond to an open/close request, so increase the time kernel will wait for response (1 ms to 10ms). Also, properly clean up a channel on a failed open, by calling the channel close routine. Just freeing the memory isn't sufficient, the device needs to be informed that the channel is no longer open, and the device memory cleared of references to freed dma buffer.
