From 04de0816173c86948b75da93a6344a0a02bbec4d Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Tue, 20 Apr 2010 14:49:01 +0200 Subject: pcmcia: pcmcia_dev_present bugfix pcmcia_dev_present is in and by itself buggy. Add a note specifying why it is broken, and replace the broken locking -- taking a mutex is a bad idea in IRQ context, from which this function is rarely called -- by an atomic_t.
