From b4b90c659d88d09dcb4e34dce5123458cb1b5071 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Tue, 10 Nov 2009 09:18:06 +0100 Subject: regulator/mc13783: rename source file to match other drivers One annoying thing about the old name was that the module was just called mc13783 which caused wrong expectations (at least for me).
