I'd make these log messages dev_info() or something.quoted
dev_info() ? It'lll just make boot noisier for no good reason. Which user wants to see this during boot up ? That's a debugging feature for develop IMHO.Most of the registers appeared to be chip revision information which is most definitely useful to tell people about, though possibly with neater formatting ("why is this batch of boards failing... oh, right"). If they're fixed device IDs then the driver should instead be verifying that the registers contain the expected values and bombing out if they don't. Either way dev_dbg() isn't too helpful.
I still beg to differ. Even if it fails, dmesg will still contain the message (provided you have it enabled). I really don't think we want this to print to console on every boot. If you're still testing your new batch of boards, you're not just a simple user and you will have debugging enabled anyway. dev_info() will be visible to anyone who's got a console running. Not sure how useful that would be to my neighbor. -- balbi -------------- next part -------------- A non-text attachment was scrubbed...
