Subject: [PATCH] brcmfmac: add possibility to obtain firmware error
|
|
|
|
The feature module needs to evaluate the actual firmware error return
|
|
upon a control command. This adds a flag to struct brcmf_if that the
|
|
caller can set. This flag is checked to determine the error code that
|
|
needs to be returned.
|
|
|
|
Fixes: b69c1df47281 ("brcmfmac: separate firmware errors from i/o errors")
