When attaching an imx28 or imx53 in USB gadget mode to a Windows host and
starting a rndis connection we see this message every 4-10 seconds:
g_ether gadget: high speed config #2: RNDIS
Analysis shows that each time this message is printed, the rndis connection is
re-establish due to a reset because of a stalled endpoint (ep 0, dir 1). The
endpoint is stalled because the reqeust complete bit on that endpoint is set,
but in isr_tr_complete_low() the endpoint request list (mEp->qh.queue) is
empty.
This patch removed this check, because the code doesn't take the following
situation into account:
The loop over all endpoints in isr_tr_complete_handler() will call ep_nuke() on
both ep0/dir0 and ep/dir1 in the first loop. Pending reqeusts will be flushed
and completed here. There seems to be a race condition, the request is nuked,
but the request complete bit will be set, too. The subsequent check (in
ep0/dir1's loop cycle) for endpoint request list (mEp->qh.queue) empty will
fail.
Both other mainline chipidea drivers (mv_udc_core.c and fsl_udc_core.c) don't
have this check.

This patch changes the setup of the endpoint maxpacket size. All non control
endpoints are initialized with an undefined ((unsigned short)~0) maxpacket
size. The maxpacket size of Endpoint 0 will be kept at CTRL_PAYLOAD_MAX.
Some gadget drivers check for the maxpacket size before they enable the
endpoint, which leads to a wrong state in these drivers.

Previously the return value from tpci200_interrupt was not quite correct
if a slot had caused an interrupt but no handler was instellalled:
IRQ_NONE was returned. However in this case we react to the interrupt
by disabling the IPack device interrupt.
Basically there are two cases the code now distinguishes:
- The tpci200 has raised an interrupt. We handle it and return
IRQ_HANDLED.
- Our device did not raise an interrupt. We return IRQ_NONE.

On transactions with n>=2 bytes, the controller actually wrongly clocks in n+1
bytes. This is caused by the (wrong) assumption that RFE in the Status Register
is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to
the implementation of synchronized byte ordering, e.g.:
Dummy-TX - RX - Dummy-TX - RX - ...
But since RFE actually stays high after some Dummy-TX, it rather looks like:
Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX)
The last RX byte is clocked in by the bus controller, but ignored by the kernel
when filling the userspace buffer.
This patch fixes the issue by asking for RX via Dummy-TX asynchronously.
Introducing a separate counter for TX bytes.

The driver uses be16_to_cpu and cpu_to_be16 to convert data in SMBus word
operations from chip to host byte order. However, the data passed from and to
the SMBus word API functions is in host byte order, not in chip byte order.
Conversion should therefore use swab16 instead of be16 to change the byte order.

solve the problem.

While registering the thermal zone, it is required to have the cooling
devices already setup, so that the .bind callback can succeed.
Due to that, the driver code needs to be reorganized so that we first
setup the cooling devices then the zones. This way we cope with the
right thermal framework initialization sequence.
This patch changes the order of the thermal zone initialization,
so that we create it only when the cooling devices are available.
It also adds some defensive checks for the config data, so that
the callbacks are ready for calls when the data is still not
initialized.

The comedi core always calls the 'do_cmdtest' function before it
calls the 'do_cmd' function. The 'do_cmdtest' for this driver calls
i8253_cascade_ns_to_timer_2div() to validate the cmd->convert_arg.
This call sets the dev_private 'div1' and 'div2' values needed to
program the 8254 timer. There is no need to call the i8253 function
a second time in the do_cmd function.

All of the comedi drivers that support the 'cmd' callback also
require a 'do_cmdtest' callback. The do_cmdtest validates the
comedi_cmd before it is executed.
"Step 1" of each do_cmdtest does a trivial validation of the
trigger sources by doing something like this for each trigger:
int err = 0;
unsigned int tmp;
tmp = cmd->start_src;
src &= TRIG_NOW;
if (!src || tmp != src)
err++;
/* Test the remaining triggers similarly */
if (err)

drm/i915: assert that the IBX port transcoder select w/a is implemented
Unfortunately I've failed to notice that these checks are not just
called for the port that is about to be disabled, but for all (which
makes sense for an assert ...), and the WARN missfired when disabling
another pipe than the one with the dp port.
Hence also check whether the port is actually disabled.
