From a5186e997524578b4ba91390ad947c767450dac8 Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Tue, 24 Nov 2009 23:11:32 +0100 Subject: [PATCH] rt2x00: Fix padding bug on L2PAD devices. While reviewing the l2pad function to align both the header and the payload on a DMA-capable boundary a bug was discovered where the payload would not be properly aligned. The header_align value was used where the payload_align value should have been used. Signed-off-by: Gertjan van Wingerde Signed-off-by: John W.
