Subject: [PATCH v3 4/4] gpiolib: acpi: Convert pin_index to be u16
Date: Mon, 2 Nov 2020 21:17:22 +0200 [thread overview]
Message-ID: <20201102191722.81502-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20201102191722.81502-1-andriy.shevchenko@linux.intel.com>
As defined by ACPI the pin index is 16-bit unsigned integer.
Define the variable, which holds it, accordingly.
