Subject: [PATCH 08/21] header: backport devm_acpi_dev_add_driver_gpios()
Date: Tue, 22 Aug 2017 00:28:04 +0200 [thread overview]
Message-ID: <20170821222817.17376-9-hauke@hauke-m.de> (raw)
In-Reply-To: <20170821222817.17376-1-hauke@hauke-m.de>
This is used by some NFC drivers to get information from the ACPI.
This was added in kernel 4.13, but backporting it to older kernel
versions than 3.19 is hard because such old kernel versions do not even
have struct acpi_gpio_mapping. This only adds the empty version of this
function as this normally needed some extra support in the generic ACPI
code and I do not care about this functionality.
