Subject: ACPI / EC: Add HP Folio 13 to ec_dmi_table in order to skip DSDT scan
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.
