| Subject: ACPI / EC: Add HP Folio 13 to ec_dmi_table in order to skip DSDT scan |
| |
| From: Lan Tianyu <tianyu.lan@intel.com> |
| |
| 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. |
