Subject: ACPI: use acpi_device_hid() when possible
X-Git-Tag: v2.6.32-rc1~18^2~2^2~6
X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=ea8d82fd316208bd0ffe6f64823d04bcb8c57158;p=net-next-2.6.git

ACPI: use acpi_device_hid() when possible

Use acpi_device_hid() rather than accessing acpi_device.pnp.hardware_id
directly.
