From d9bb8326fa2cb6f964a6dcdf841e2e9551ee7899 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 7 Dec 2014 21:53:20 +0000 Subject: kernel: update bcma and ssb to wireless-testing master-2014-12-05 This brings ssb and bcma to wireless-testing tag master-2014-12-05 In addition it also adds the ARM-BCM5301X-Add-IRQs-to-Broadcom-s-bus- axi-in-DTS-f.patch which adds the irq number in a way it is done in the mainline kernel.
