[media] media: omap4iss: csi2: Fix IRQ handling when stopping module

When stopping the CSI2 receiver the s_stream handler will wait for the
IRQ handler to notice the stop request. The receiver, automatically
disabled by the hardware after each frame, is then not reenabled by the
IRQ handler as it returns immediately.

As the IRQ handler check is performed before handling the context IRQ,
the context IRQ source isn't cleared, and the CSI2 IRQ is then fired
again immediately. The IRQ handler then fails to notice that the module
is being stopped, processes the IRQ normally and reenables the CSI2
hardware.

The problem goes unnoticed at stream stop time, but depending on the IRQ
and s_stream scheduling timings, the CSI2 receiver can end up being
hanged and will not produce any interrupt the next time it gets enabled,
despite being soft-reset then.

Fix this by checking for module stop after clearing the context IRQ
source.

regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).

So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.

But this means that OF-only drivers needs to have both OF and SPI id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same SPI device name for example.

To avoid the above, the SPI core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

[media] v4l2-clk: v4l2_clk_get() also need to find the of_fullname clock

The soc-camera host will be probed and register a v4l2_clk, but if at
that moment, the i2c device is not available, then the registered
v4l2_clk name is an OF string not a I2C string.

So when i2c sensor probes and calls v4l2_clk_get(), it only searches a

This patch will search the clock with OF string name if no clock with
I2C string name could be found.

[media] media: fix waitqueue_active without memory barrier in cpia2 driver

cpia2_usb_disconnect() seems to be missing a memory barrier which might
cause the waker to not notice the waiter and miss sending a wake_up as
in the following figure.

mutex_unlock(&cam->v4l2_lock);

The attached patch removes the call to waitqueue_active() leaving just
wake_up() behind.  This fixes the problem because the call to
spin_lock_irqsave() in wake_up() will be an ACQUIRE operation.

I found this issue when I was looking through the linux source code
for places calling waitqueue_active() before wake_up*(), but without
preceding memory barriers, after sending a patch to fix a similar
issue in drivers/tty/n_tty.c  (Details about the original issue can be

[media] vb2: fix a regression in poll() behavior for output,streams

In the 3.17 kernel the poll() behavior changed for output streams:
as long as not all buffers were queued up poll() would return that
userspace can write. This is fine for the write() call, but when
using stream I/O this changed the behavior since the expectation
was that it would wait for buffers to become available for dequeuing.

This patch only enables the check whether you can queue buffers
for file I/O only, and skips it for stream I/O.
