---------------------------
-What: read_dev_chars(), read_conf_data{,_lpm}() (s390 common I/O layer)
-When: December 2007
-Why: These functions are a leftover from 2.4 times. They have several
- problems:
- - Duplication of checks that are done in the device driver's
- interrupt handler
- - common I/O layer can't do device specific error recovery
- - device driver can't be notified for conditions happening during
- execution of the function
- Device drivers should issue the read device characteristics and read
- configuration data ccws and do the appropriate error handling
- themselves.

What: i2c-ixp2000, i2c-ixp4xx and scx200_i2c drivers

Why: Obsolete. The new i2c-gpio driver replaces all hardware-specific
