Subject: [PATCH 3/4] ath9k: fix a crash in the PA predistortion apply function
Date: Fri, 30 Jul 2010 21:02:11 +0200 [thread overview]
Message-ID: <1280516532-42721-3-git-send-email-nbd@openwrt.org> (raw)
In-Reply-To: <1280516532-42721-2-git-send-email-nbd@openwrt.org>
When updating the PAPRD table in hardware, PAPRD itself needs to be
disabled first, otherwise the hardware can throw a data bus error,
which upsets at least some platforms.
