From 621a5f7ad9cd1ce7933f1d302067cbd58354173c Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Sat, 26 Sep 2015 15:04:07 -0700 Subject: debugfs: Pass bool pointer to debugfs_create_bool() Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.
