From: Marc Dietrich Date: Sun, 24 Jun 2012 21:25:20 +0000 (+0200) Subject: staging: nvec: rename led driver to board specific paz00 driver X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac562680577a28fa98ebecebff5e5097ccf9a9d2;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git staging: nvec: rename led driver to board specific paz00 driver The led driver used OEM commands which are not part of the nvec protocol definition. Therefore it is renamed to nvec_paz00 to reflect that it only applies to PAZ00 board based devices.
