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