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.
