[ 10/18] ACPI / EC: Add HP Folio 13 to ec_dmi_table in order to skip DSDT scan

[Greg Kroah-Hartman]

3.0-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.
