318What: read_dev_chars(), read_conf_data{,_lpm}() (s390 common I/O layer)
319When: December 2007
320Why: These functions are a leftover from 2.4 times. They have several
321 problems:
322 - Duplication of checks that are done in the device driver's
323 interrupt handler
324 - common I/O layer can't do device specific error recovery
325 - device driver can't be notified for conditions happening during
326 execution of the function
327 Device drivers should issue the read device characteristics and read
328 configuration data ccws and do the appropriate error handling
329 themselves.
