Just revert this hunk. Not sure about the drv->register check. I'd prefer to revert the old code and let driver_attach return the amount of found devices. KAbi shouldn't be a problem as we want to have this in mainline anyway. Hmm as said I am not sure, just let it, it should be ok. Can you mail the next patch per mail pls. If you like to post this to linux-acpi list, CC Len Brown and me, pls. Check carefully which tags you should add (there is a howto somewhere how to commit patches to lkml). Some things: Add a [PATCH] tag at the beginning of subject. If you have several patches you should post like [PATCH 0/2] -> descriptive mail [PATCH 1/2] -> first of 2 patches . Best is you also add something like: Len can this be applied, pls. Ahh yes. lkml people want to have patches inlined at the end of mail. Len likes to have them as attachment. I normally inline and attach them. Then there should come something like this: Subject: 1 line description of patch description signed-off-by's (that is you and you can also put me in ..) diffstat patch -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
