From: Bob Moore Date: Mon, 23 Feb 2009 07:02:07 +0000 (+0800) Subject: ACPICA: Rename ACPI bit register access functions X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=50ffba1bd3120b069617455545bc27bcf3cf7579;p=linux-2.6-omap-h63xx.git ACPICA: Rename ACPI bit register access functions Rename acpi_get_register and acpi_set_register to clarify the purpose of these functions. New names are acpi_read_bit_register and acpi_write_bit_register.
