From f61044a9b0f37cfee8b2ce0d205403115b7e0107 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Tue, 31 Jan 2017 21:00:51 +0100 Subject: kernel: rename bgmac patches to squeeze them MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a pure rename without any changes. It makes maintaining bgmac simpler and will hopefully make adding new kernel a bit easier.
