From 3970dd8c5169505f0cc5e4c3e2fde7bdd9bbad3e Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sat, 2 Jan 2010 23:19:45 +0100 Subject: pcmcia: do not lock socket driver module on card insert Do not lock the socket driver module on card insert, as the PCMCIA core can handle a socket module removal, at least if we add a call to socket_remove() on pccardd()'s shutdown.
