Subject: [PATCH] brcmfmac: modify __brcmf_err() to take bus as a parameter
|

So far __brcmf_err() was using pr_err() which didn't allow identifying
|
|
device that was affected by an error. It's crucial for systems with more
|
|
than 1 device supported by brcmfmac (a common case for home routers).
|
|
|
|
This change allows passing struct brcmf_bus to the __brcmf_err(). That
|
|
struct has been agreed to be the most common one. It allows accessing
|
|
struct device easily & using dev_err() printing helper.
