From: Uwe Kleine-König Date: Tue, 10 Nov 2009 08:18:06 +0000 (+0100) Subject: regulator/mc13783: rename source file to match other drivers X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b4b90c659d88d09dcb4e34dce5123458cb1b5071;p=deliverable%2Flinux.git 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).
