This is an expected error given the lack of the firmware so emit it at KERN_NOTICE and not KERN_ERROR. Also include the firmware URL in the user facing message so that the user can investigate and fix the issue on their own, and also explain the consequence in plain language. The complete failure message, including the first line from the firmware loader, becomes i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1.bin failed with error -2 i915 0000:00:02.0: Failed to load DMC firmware [https://01.org/linuxgraphics/intel-linux-graphics-firmwares], disabling runtime power management.
