The SCmdLinkStatus struct has a couple holes.  There is one between
->bLink and ->wBSSType, and another between ->abySSID and ->uChannel.

I've added a memset() to initialize the struct to zero.  Since we don't
need to clear abySSID any more so I've removed that memset.  It was
wrong anyway: abySSID has "SSID_MAXLEN + 2" (34) bytes, not
"WLAN_SSID_MAXLEN + 1" (33).

I screwed up the sense of this if() statement while porting our
vendor driver to create the dwc2 driver. This caused frame overrun
errors on periodic transfers when there were other transfers
active in the same (micro)frame.

With this fix, the dwc2 driver now works on the Raspberry Pi
platform even with the USB Ethernet controller enabled, where
before that would cause all USB devices to stop working.

Thanks to Ray Jui and Jerry Lin at Broadcom for tracking this down.

__sync_fetch_and_and and __sync_fetch_and_or are functions that are provided
by gcc and depending on the target architecture may be implemented in libgcc,
which is not always available in the kernel. This leads to a build failure
on ARMv5:

drivers/built-in.o: In function `line6_pcm_release':
:(.text+0x3bfe80): undefined reference to `__sync_fetch_and_and_4'
drivers/built-in.o: In function `line6_pcm_acquire':
:(.text+0x3bff30): undefined reference to `__sync_fetch_and_or_4'

To work around this, we can use the kernel-provided cmpxchg macro.

Build-tested only.

As suggested by Ian Abbott, comedi_set_spriv() can only be used to
set the subdevice->private pointer to something that can be kfree()'d.
Rename the function to comedi_alloc_spriv() and have it kzalloc() the
memory as well as set the private pointer. This saves a function call
in the drivers and avoids the possibility of incorrectly calling
comedi_set_spriv() for some pointer that is not meant to be kfree()'d.
