From 5ed0d32805c19cfa5f03a25ec7e041dc845d3062 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 10 Jun 2025 16:38:16 +0200 Subject: [PATCH] Documentation: gpio: undocument removed behavior Since commit 700cdf7ed00f ("gpio: sysfs: make the sysfs export behavior consistent"), named GPIO lines are no longer exported in sysfs as links named after the them. Drop the misleading bit from the ABI docs.
