b7cd2d9fdc staging/mei: don't check if list is empty before looping
1. No need to check if a list is empty before list_for_each_ looping as
this is already checked by loop stopping conditional.

The side effect is reduced indentation depth
from:
	if (!list_empty)
		list_for_each()
to:
	list_for_each()

2. drop cb_ prefix from cl_pos, cl_next variables used in list_for_each
loops. The code is more compact and readable

dfd8ee92a9 Staging: comedi: fix integer overflow in do_insnlist_ioctl()
There is a potential integer overflow in do_insnlist_ioctl() if
userspace passes in a large insnlist.n_insns.  The call to kmalloc()
would allocate a small buffer, leading to a memory corruption.

The bug was reported by Dan Carpenter <dan.carpenter@oracle.com>
and Haogang Chen <haogangchen@gmail.com>.  The patch was suggested by
Ian Abbott <abbotti@mev.co.uk> and Lars-Peter Clausen <lars@metafoo.de>.

Since CH_Agere_Systems_Mini_PCI_V1 is defined as 0 in hermes_pci_versions
and neither the enum nor the value is used anywhere else, we can drop
the assignment of .driver_data as it is initialized as 0 by default.

c64391f264 usb/isp1760: Fix race condition memory leak
This fixes a memory leak reported by Catalin Marinas:

schedule_ptds() is called from isp1760_irq() and removes the qh from the
controlqhs queue but ep->hcpriv still points to the qh and therefore it is not
freed.

Shortly after this, the isp1760_endpoint_disable() function sets ep->hcpriv to
NULL and calls schedule_ptds() but since the corresponding qh is no longer in
the queue, it is simply forgotten and reported by kmemleak.

With this patch, the qh is always freed at endpoint_disable, instead, and the
corresponding entry removed from the queue head list.

While I was at it, I also replaced the lines in isp1760_endpoint_disable()
that removed remaining qtds from the qh with a WARN_ON check for non-empty qh,
in line with earlier comments from Alan Stern (linux-usb list, 2011-07-20).
