Oh yeah, ath10k definitely needs this! It tries different firmware API
versions from latest to older (firmware-6.bin, firmware-5.bin,
firmware-4.bin and so on) to find a compatible firmware and the error
messages from request_firmware() are constantly confusing the users, I
think the latest query about these errors from last week on IRC. So
having request_firmware_nowarn() (or similar) would help users a lot.
We tried to workaround this by using request_firmware_direct() (which
oddly doesn't print anything) but that caused issues with OpenWRT/LEDE:
And iwlwifi has a similar problem, adding Luca to the loop.
