From: Rafael J. Wysocki <rjw@xxxxxxx> Revert a hunk in drivers/net/wireless/ath/ath9k/hw.c introduced by commit 2577c6e8f2320f1d2f09be122efef5b9118efee4 (ath9k_hw: Add support for AR946/8x chipsets) that caused a nasty regression to appear on my Acer Ferrari One (the box locks up entirely at random times after the wireless has been started without any way to get debug information out of it).
