   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.
