From: Rafał Miłecki <rafal@milecki.pl>

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.

This is my another try on improving brcmf_err after the failure from 2
years ago:
[PATCH V3 4/9] brcmfmac: add struct brcmf_pub parameter to the __brcmf_err
https://patchwork.kernel.org/patch/9553255/

Back then my change has been rejected due to miscommunication and late
realisation that struct brcmf_pub (a previous choice instead of struct
brcmf_bus) was a bad idea. Back then Arend wrote:
> So I would think using struct brcmf_bus in brcmf_err() would be best
> fit.

So this patch follows that suggestion & updates __brcmf_err()
accordingly.

From: Rafał Miłecki <rafal@milecki.pl>

This enables dev_err() usage (instead of pr_err()) in the __brcmf_err().
It makes error messages more meaningful and is important for debugging
errors/bugs on systems with multiple brcmfmac supported devices.

All other files should follow & get updated similarly (soon).

Ideally all files should get updated at the same time but I'm reluctant
to work on that until I see my changes accepted. There are over 500
occurrences of brcmf_err() and I'll loose hours again if someone nacks
this.

Thus the safe way - updating a single file only as for now. I promise to
work on the rest of the code as soon as it hits the Kalle's tree. Sounds
acceptable?

Thanks, Rafał

Little less than two years ago I played with your idea and using GCC 
builtin __builtin_types_compatible_p(t1,t2). Anyway, it looks good. So 
you want to limit it to brcmf_err() or brcmf_dbg() as well?

Regards,
Arend

Hi Rafał,

So I was in doubt about this file. I was thinking about using 
wiphy_err() for this file. Hmmm, now that I think of it that was my idea 
for the whole common driver (so not bus-specific part), which I is why I 
moved wiphy_new() to beginning of brcmf_attach() a while ago. Even 
better would be using wdev_err() in this file, but that does not exist 
:-) For the bus-specific sources using dev_err() is fine.

Regards,
Arend

I believe all messages printed by brcmfmac should specify a device.
brcmf_err, brcmf_info & brcmf_dbg.

I can work on brcmf_info & brcmf_dbg once I get done with brcmf_err :)

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.

From: Rafał Miłecki <rafal@milecki.pl>

This enables dev_err() usage (instead of pr_err()) in the __brcmf_err().
It makes error messages more meaningful and is important for debugging
errors/bugs on systems with multiple brcmfmac supported devices.

All bus files should follow & get updated similarly (soon).
