From 8960400eeefa73e7fe32dc2b6b5ac529d43a9593 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 26 Jun 2013 09:55:54 +0200 Subject: [PATCH] b43: replace B43_BCMA_EXTRA with modparam allhwsupport MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This allows enabling support for extra hardware with just a module param, without kernel/module recompilation.
