3 Subject: [PATCH] ath10k: Don't initialize devices asynchronously
4  
5 OpenWrt requires all PHYs to be initialized to create the configuration files
6 during bootup. ath10k violates this because it delays the creation of the PHY
7 to a not well defined point in the future.
8  
9 Forcing the work to be done immediately works around this problem but may also
10 delay the boot when firmware images cannot be found.
