From 1fba49741dc50d13d2fe6cf04f5a547e6c5c81f6 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Thu, 8 Oct 2009 21:56:32 +0300 Subject: wl1271: Use vmalloc to allocate memory for firmware Use vmalloc to allocate memory for the firmware image, and use a smaller linear buffer for the actual transfer of the firmware to the chipset. This patch is an adaptation of a similar patch for wl1251 by Kalle Valo. Signed-off-by: Juuso Oikarinen Reviewed-by: Luciano Coelho Signed-off-by: Luciano Coelho Signed-off-by: John W.
