    Subject[PATCH 023/104] ACPI / EC: Add HP Folio 13 to ec_dmi_table in order to skip DSDT scan
    Date
    3.5.7.22 -stable review patch.  If anyone has any objections, please let me know.

    ------------------

    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.
