I would very much prefer them to go via your tree. Unfortunately it seems like kbuild test robot found an incorrect printk format specifier in one of the debug prints. Line 838 dev_dbg(dev, "efuse read(%s) = %x, bytes %ld\n", cname, *data, len); should be dev_dbg(dev, "efuse read(%s) = %x, bytes %zd\n", cname, *data, len); So %zd rather than %ld. This was obviously an error, but didn't show when compiling on arm64 or x86_64. Sorry for this inconvenience. Could you fix up the commit or do I need to do a respin? Kind regards, Niklas

Hello Rafael, Since the intel test robot found another problem, I decided to cook up a series that can be applied (or squashed) on top of your bleeding-edge branch here instead: https://patchwork.kernel.org/project/linux-pm/list/?series=220955 Again, sorry for the inconvenience.
