From 6f6835beab99c770f1cc6de99b3e3b73c333dec7 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 2 Sep 2025 13:59:21 +0200 Subject: [PATCH] pinctrl: qcom: use generic pin function helpers With the pinmux core no longer duplicating memory used to store the struct pinfunction objects in .rodata, we can now use the existing infrastructure for storing and looking up pin functions in qualcomm drivers. Remove hand-crafted callbacks.
