Message-Id: <1219008563.28339.15.camel@pasglop> Date: Mon, 18 Aug 2008 07:29:23 +1000 From: Benjamin Herrenschmidt <benh@...nel.crashing.org> To: Jeff Garzik <jgarzik@...ox.com> Cc: netdev <netdev@...r.kernel.org>, linuxppc-dev list <linuxppc-dev@...abs.org>, Sebastian Siewior <bigeasy@...utronix.de> Subject: [PATCH] ibm_newemac: Don't call dev_mc_add() before device is registered We must not call dev_mc_add() from within our HW configure which happens before we initialize and register the netdev. Do it in open() instead. Thanks to Sebastian Siewior for tracking it down. Signed-off-by: Benjamin Herrenschmidt <benh@...nel.crashing.org> --- This fixes an uninitialized spinlock warning (and possibly more). Please apply. Cheers, Ben.
