From 3d74c9eca1a2bda03e45f18d13154ac3e0dfba85 Mon Sep 17 00:00:00 2001 From: Matt Ranostay Date: Thu, 20 Oct 2022 23:30:00 +0800 Subject: [PATCH] HID: mcp2221: correct undefined references when CONFIG_GPIOLIB isn't defined Singular #ifdef IS_REACHABLE(CONFIG_GPIOLIB) weren't covering all the gpiolib functions that were being referenced. Update the code regions that are commented out when CONFIG_GPIOLIB isn't enabled to avoid errors.
