The patch titled
Char: mxser_new, fix twice resource releasing
has been removed from the -mm tree. Its filename was
char-mxser_new-fix-twice-resource-releasing.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Char: mxser_new, fix twice resource releasing
From: Jiri Slaby <jirislaby@xxxxxxxxx>
Because brd->info is not NULLed, resources are released twice. NULL it in
pci_remove function. Also take care of retval and releasing in pci_probe --
mxser_initbrd alreasy releases resource, do not do it again in fail path in
probe function.
