From 0b35a45bde561d67ffd83b352764b48f936f46bb Mon Sep 17 00:00:00 2001 From: Holger Brunck Date: Mon, 19 Dec 2011 17:49:48 +0100 Subject: ARM: plat-orion: make gpiochip label unique The former implementation adds a fix gpiochip label string to the framework. This is confusing because orion_gpio_init is called more than once and this ends up in different gpiochips with the same label. This patch adds the already present orion_gpio_chip_count to the label string to make it unique in the system.
