From c62e0658d458d8f100445445c3ddb106f3824a45 Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Thu, 29 Jan 2026 15:59:44 +0100 Subject: gpiolib: acpi: Fix gpio count with string references Since commit 9880702d123f2 ("ACPI: property: Support using strings in reference properties") it is possible to use strings instead of local references. This work fine with single GPIO but not with arrays as acpi_gpio_package_count() didn't handle this case. Update it to handle strings like local references to cover this case as well.
