From 24fc32b35647401bbf03b3e2d5f01c6d0579a01c Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Wed, 7 Mar 2012 20:03:58 +0200 Subject: [PATCH] ath6kl: add ath6kl_bmi_write_hi32() We have a lot of 32 bit writes to the host interest area and the code doing that is ugly. Clean that up by adding ath6kl_bmi_write_hi32(). This also fixes few checkpatch warnings.
