We are trying to enable -Wformat for clang in 6.0 and this instance of that warning was introduced this development cycle by commit 323aa1f093e6 ("ASoC: SOF: Add a new IPC op for parsing topology manifest"). If I am tracking all my patches correctly, this is the only instance of -Wformat that does not have a patch applied to a maintainer's tree so it would be really unfortunate if we could not sure it on for -rc1. We could probably route this via the Kbuild tree with an Ack along with the patch that enables -Wformat if it cannot go via Mark's or Takashi's ree. Cheers, Nathan

We have a couple of months to get fixes into the next release so it's not an emergency at this point. If you want people to see things promptly you really need to do things like send them with subject lines that look like something that might be relevant for them to review (generally, at least visually resemble how other commits in the area look). I don't know if I even opened this mail first time around because based on the subject it looks like something for drivers/soc not a subsystem I maintain. Given that none of the SOF people responded it's likely something similar applied there. In any case, if you think something's been lost the content free pings either here or on IRC aren't that helpful - they're not directly actionable. It is generally more helpful to resend, that way people have the patch to hand and don't need to go looking for it.
