Subject: [PATCH 1/4] led: trig: netdev: Fix requesting offload device
|
|
|
|
When the netdev trigger is activates, it tries to determine what
|
|
device the LED blinks for, and what the current blink mode is.
|
|
|
|
The documentation for hw_control_get() says:
|
|
|
|
* Return 0 on success, a negative error number on failing parsing the
|
|
* initial mode. Error from this function is NOT FATAL as the device
|
|
* may be in a not supported initial state by the attached LED trigger.
|
|
*/
|
|
|
|
For the Marvell PHY and the Armada 370-rd board, the initial LED blink
|
|
mode is not supported by the trigger, so it returns an error. This
|
|
resulted in not getting the device the LED is blinking for. As a
|
|
result, the device is unknown and offloaded is never performed.
|
|
|
|
Change to condition to always get the device if offloading is
|
|
supported, and reduce the scope of testing for an error from
|
|
hw_control_get() to skip setting trigger internal state if there is an
|
|
error.
