3.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Lan Tianyu <tianyu.lan@xxxxxxxxx> commit eff9a4b62b14cf0d9913e3caf1f26f8b7a6105c9 upstream. HP Folio 13's BIOS defines CMOS RTC Operation Region and the EC's _REG method will access that region. To allow the CMOS RTC region handler to be installed before the EC _REG method is first invoked, add ec_skip_dsdt_scan() as HP Folio 13's callback to ec_dmi_table.
