[Git Patch] ACPI: Fix a warning of discarding qualifiers from pointer target type

[WANG Cong <xiyou.wangcong@gmail.com>]

Fix this warning:

drivers/acpi/ec.c: In function `acpi_ec_ecdt_probe':
drivers/acpi/ec.c:873: warning: passing arg 1 of `acpi_get_devices' discards qualifiers from pointer target type

(I don't know whether this fix hits the real problem.)
