 ---------------------------
 
-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
