From fa54b326803d91b04705a6adf0ff963593a9fe5c Mon Sep 17 00:00:00 2001 From: Aaron Sierra Date: Fri, 29 Apr 2016 16:41:02 -0500 Subject: vme: change LM callback argument to void pointer Make the location monitor callback function prototype more useful by changing the argument from an integer to a void pointer. All VME bridge drivers were simply passing the location monitor index (e.g. 0-3) as the argument to these callbacks. It is much more useful to pass back a pointer to data that the callback-registering driver cares about. There appear to be no in-kernel callers of vme_lm_attach (or vme_lme_request for that matter), so this change only affects the VME subsystem and bridge drivers. This has been tested with Tsi148 hardware, but the CA91Cx42 changes have only been compiled.
