Re: printk(KERN_x...) vs dev_x()

At some places in the code, there is no valid 'dev' pointer to pass to dev_xx() macro, at such places is it ok to use printk(KERN_XXX...)?

pr_debug() is the equivalent you want. Ideally tweak the code so the dev pointer is available. I know that right now is a bit of a problem in a few cases (some tty stuff for example only just acquired a usable dev pointer) Alan -- Linus Torvalds
