There are a number of drivers that use "module_init(init)" and "module_exit(exit)", which are anonymous names and can lead to confusion or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log. Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names.
I'm not fully sure about the Fixes tags but I don't see that it hurts anything. For the series: Reviewed-by: Ira Weiny <redacted>
