From 5af4f8349c5984e73ae85ab0328f8e229cf9e2f7 Mon Sep 17 00:00:00 2001 From: Gilad Ben-Yossef Date: Tue, 12 Dec 2017 14:52:55 +0000 Subject: [PATCH] staging: ccree: fix reg mgr naming convention The request manager files were using a func naming convention which was inconsistent (ssi vs. cc), included a useless prefix (ssi_request_mgr) and often too long. Make the code more readable by switching to a simpler, consistent naming convention.
