From 2b3374306b315be02db0f67d3102a0d1e1357270 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Thu, 28 Oct 2021 09:35:48 -0700 Subject: [PATCH] drm/bridge: sn65dsi86: ti_sn65dsi86_read_u16() __maybe_unused When built without CONFIG_PWM there are no references to ti_sn65dsi86_read_u16(), avoid the W=1 build warning by marking the function as __maybe_unused. __maybe_unused is used insted of a #ifdef guard as it looks slighly cleaner and it avoids issues if in the future other permutations of the config options would use the function.
