From: Rafał Miłecki <[email protected]> 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.
