Subject: [PATCH RFC/RFT 01/15] Documentation: gpio: undocument removed
 behavior

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

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.
