+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.
