Thank you for your review!
I don't agree that this doesn't fix a bug:
}
dev_err(dai->dev, "%s:%s DATA connection missing\n",dai->name, module->name);Using 'module' when data == NULL is *guaranteed* to be a type confused bogus pointer. It fundamentally can never be correct.
Ah. I did not read all the way to the end of the patch.
The bugfix needs to be sent as it's own patch. Just the one liner. It needs a fixes tag as well.
[PATCH] staging: greybus: fix Oops in error message
The "module" pointer is invalid here. It's the list iterator and we exited the loop without finding a valid entry.
Fixes: 6dd67645f22c ("greybus: audio: Use single codec driver registration") Signed-off-by: You
if (!data) { - dev_err(dai->dev, "%s:%s DATA connection missing\n", - dai->name, module->name); + dev_err(dai->dev, "%s DATA connection missing\n", + dai->name); mutex_unlock(&codec->lock);
We're happy to apply the other stuff as well, but we don't mix cleanups and bug fixes like that.
