From 27fe971d08b43f649358745a55f3c48ac6f413f8 Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Fri, 30 Apr 2010 09:45:51 -0600 Subject: viafb: Do not remove gpiochip under spinlock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gpiochip_remove() is not meant to be called with interrupts disabled, and there is no need for the lock here in any case.
