1a6635f729 USB: serial: spcp8x5.c: remove debug module parameter
Now that the dbg() macro is no longer being used in the driver,
the debug module parameter doesn't do anything at all.  So remove
it so as to not confuse people.

f80e866f72 xHCI patches for 3.7
Hi Greg,
 
 Here's seven patches for 3.7.
 
 The first four fix an issue with Set Address command timeouts.  It turns out
 that Set Address timeouts can trigger a warning that was put in to avoid a NULL
 pointer dereference.  This patchset fixes the underlying cause of the NULL
 pointer that was papered over by the warning.  They should be applied to stable,
 but I'm a bit nervous about the size, so I'd rather they go into 3.7, rather
 than trying to stuff them into a late 3.6-rc.
 
 The other three patches are various trivial fixes.

b63f4053cc xHCI: handle command after aborting the command ring
According to xHCI spec section 4.6.1.1 and section 4.6.1.2,
after aborting a command on the command ring, xHC will
generate a command completion event with its completion
code set to Command Ring Stopped at least. If a command is
currently executing at the time of aborting a command, xHC
also generate a command completion event with its completion
code set to Command Abort. When the command ring is stopped,
software may remove, add, or rearrage Command Descriptors.

To cancel a command, software will initialize a command
descriptor for the cancel command, and add it into a
cancel_cmd_list of xhci. When the command ring is stopped,
software will find the command trbs described by command
descriptors in cancel_cmd_list and modify it to No Op
command. If software can't find the matched trbs, we can
think it had been finished.

This patch should be backported to kernels as old as 3.0, that contain
the commit 7ed603ecf8 "xhci: Add an
assertion to check for virt_dev=0 bug." That commit papers over a NULL
pointer dereference, and this patch fixes the underlying issue that
caused the NULL pointer dereference.

6e4468b9a0 xHCI: cancel command after command timeout
The patch is used to cancel command when the command isn't
acknowledged and a timeout occurs.

the commit 7ed603ecf8 "xhci: Add an
assertion to check for virt_dev=0 bug." That commit papers over a NULL

b92cc66c04 xHCI: add aborting command ring function
Software have to abort command ring and cancel command
when a command is failed or hang. Otherwise, the command
ring will hang up and can't handle the others. An example
of a command that may hang is the Address Device Command,
because waiting for a SET_ADDRESS request to be acknowledged
by a USB device is outside of the xHC's ability to control.

To cancel a command, software will initialize a command
descriptor for the cancel command, and add it into a
cancel_cmd_list of xhci.

Sarah: Fixed missing newline on "Have the command ring been stopped?"
debugging statement.

This patch should be backported to kernels as old as 3.0, that contain
the commit 7ed603ecf8 "xhci: Add an
assertion to check for virt_dev=0 bug." That commit papers over a NULL
pointer dereference, and this patch fixes the underlying issue that

c181bc5b5d xHCI: add cmd_ring_state
Adding cmd_ring_state for command ring. It helps to verify
the current command ring state for controlling the command
ring operations.

This patch should be backported to kernels as old as 3.0.  The commit
7ed603ecf8 "xhci: Add an assertion to
check for virt_dev=0 bug." papers over the NULL pointer dereference that
I now believe is related to a timed out Set Address command.  This (and
the four patches that follow it) contain the real fix that also allows
VIA USB 3.0 hubs to consistently re-enumerate during the plug/unplug
stress tests.

fee84a54e7 USB: serial: core: remove some trace debugging calls
These dbg() calls were no more than just a function trace, so remove
them.  If you want to see the functions being called, use the in-kernel
function trace code instead, it's much nicer.
