From: Jarkko Nikula Date: Thu, 14 Nov 2013 12:03:51 +0000 (+0200) Subject: ACPI: Provide acpi_dev_name accessor for struct acpi_device device name X-Git-Tag: v3.13-rc1~28^2~11^2~3 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=45c42a7f582cc07259bc78910de8b0b1c94094d5;p=uclinux-h8%2Flinux.git ACPI: Provide acpi_dev_name accessor for struct acpi_device device name struct acpi_device fields are only available when CONFIG_ACPI is set. We may find use for dev_name(&adev->dev) in generic code that is build also without CONFIG_ACPI is set but currently this requires #ifdef CONFIG_ACPI churn. Provide here an accessor that returns dev_name of embedded struct device dev in struct acpi_device or NULL depending on CONFIG_ACPI setting. Signed-off-by: Jarkko Nikula Signed-off-by: Rafael J.
