Subject: ath9k: Check multi-channel context for WOW
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1331f5a751eb143bc7732c880bbdde4431e90a77;p=openwrt%2Fstaging%2Fblogic.git

ath9k: Check multi-channel context for WOW

If CONFIG_ATH9K_CHANNEL_CONTEXT is enabled, check whether
multiple contexts are active and if so, return 1 without
enabling WOW since we don't support it in this case.
