Smatch complains that "err" can be uninitialized if we have a zero size

When dmabuf is used for BLOB type frame, the frame
buffers allocated by gralloc will hold more pages
than the valid frame data due to height alignment.

In this case, the page numbers in sg list could exceed the

The driver apparently assumes that the device uses the same page size
as the CPU, but also assumes that this is 4096 bytes. On architectures
with a larger page size like 65536 bytes, we get a warning about an
integer overflow:

drivers/media/pci/intel/ipu3/ipu3-cio2.c: In function 'cio2_fbpt_entry_init_dummy':

   CIO2_PAGE_SIZE / sizeof(u32) * CIO2_MAX_LOPS;

Obviously this won't work, but the driver is also unlikely to ever be
used on such an architecture, so the easiest workaround is to define
the CIO2_PAGE_SIZE macro to the size that the hardware actually uses.

Some UVC video cameras contain metadata in their payload headers. This
patch extracts that data, adding more clock synchronisation information,
on both bulk and isochronous endpoints and makes it available to the user
space on a separate video node, using the V4L2_CAP_META_CAPTURE capability
and the V4L2_BUF_TYPE_META_CAPTURE buffer queue type. By default, only the
V4L2_META_FMT_UVC pixel format is available from those nodes. However,
cameras can be added to the device ID table to additionally specify their
own metadata format, in which case that format will also become available
from the metadata node.

q->num_buffers is zero and q->memory is different than memory.

That's flawed when the device is initialized, or after the
queues are freed, as it does, unnecessary calls to
__vb2_queue_cancel() and  __vb2_queue_free().

That can be avoided by making sure that q->memory is set to
VB2_MEMORY_UNKNOWN at vb2_core_queue_init(), and adding such

Pull irq fixes from Thomas Gleixner:
 "A rather large update after the kaisered maintainer finally found time
  to handle regression reports.

   - The larger part addresses a regression caused by the x86 vector
     management rework.

     The reservation based model does not work reliably for MSI
     interrupts, if they cannot be masked (yes, yet another hw
     engineering trainwreck). The reason is that the reservation mode
     assigns a dummy vector when the interrupt is allocated and switches
     to a real vector when the interrupt is requested.

     If the MSI entry cannot be masked then the initialization might
     raise an interrupt before the interrupt is requested, which ends up
     as spurious interrupt and causes device malfunction and worse. The
     fix is to exclude MSI interrupts which do not support masking from
     reservation mode and assign a real vector right away.

   - Extend the extra lockdep class setup for nested interrupts with a
     class for the recently added irq_desc::request_mutex so lockdep can
     differeniate and does not emit false positive warnings.

   - A ratelimit guard for the bad irq printout so in case a bad irq
     comes back immediately the system does not drown in dmesg spam"

 "Here are six small fixes of some of the char/misc drivers that have
  been sent in to resolve reported issues.

  Nothing major, a binder use-after-free fix, some thunderbolt bugfixes,

  linux-next with no reported issues for a while"
