From 226b2242d43d6d2d4a72e394c19fdd2f1b06f29e Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Thu, 20 Apr 2017 23:23:20 +0200 Subject: [PATCH] gpio: export add/remove lookup table functions For hot-pluggable devices adding GPIOs dynamically we need to assemble and add the gpio lookup tables at probe time in modules, so that requesting these GPIOs in attached drivers can work. Export lookup table functions for modules.
