[RFC PATCH] iwlwifi: yoyo: don't print failure if debug firmware is missing

[Wolfram Sang]

Missing this firmware is not fatal, my wifi card still works. Even more,
I couldn't find any documentation what it is or where to get it. So, I
don't think the users should be notified if it is missing. If you browse
the net, you see the message is present is in quite some logs. Better
remove it.

This is only build tested because I wanted to get your opinions first. I
couldn't find any explanation about yoyo, so I am entering unknown
territory here.

Any input on this? Or people I should add to CC?

This was discussed on another thread:

https://lkml.kernel.org/r/87mu3magfp.fsf@tynnyri.adurom.net

Unless Intel folks object I'm planning to take this to
wireless-drivers-next.

Yes, please, just go ahead and take it.  I have the same change in our
internal tree, but I didn't have the time to send it out due to my
vacations (from which I'm now back).

Despite commit 3f4600de8c93 (iwlwifi: yoyo: don't print failure if debug 
firmware is missing) being in Linux since version 5.9-rc1, I am still 
seeing this with Debian’s Linux 5.9.9.


Kind regards,

Paul
