Subject: [PATCH] brcmfmac: add a function designated for handling firmware
|
||
|
|
fails

This improves handling PCIe firmware halts by printing a clear error
|
||
|
|
message and replaces a similar code in the SDIO bus support.
|
||
|
|
|
||
|
|
It will also allow further improvements like trying to recover from a
|
||
|
|
firmware crash.
