Title:
cx23885: Incorrect argument passed to videobuf_dma_unmap
To
After discussion among the kernel team, and inspection of the patch,
here is the concensus:
This patch looks obviously correct by inspection, and should only affect users
of this device.
This kernel has been tested with a number of other PCI devices, and is not
broken for any other device.
Steve - understood. I have no HW to test this on (looks like we need a
64-bit machine with an IOMMU), so can't help out here. So, we're waiting
on the folks on bug 659348 to test.

We're going to let this go until Monday, and then we'll revert the patch
if we don't have verification that the kernel in -proposed resolves the
issue.

SRU Justification:
Impact: Currently, the kernel build produces a warning on the
cx23885-core.c:
drivers/media/video/cx23885/cx23885-core.c: In function ‘cx23885_free_buffer’:
drivers/media/video/cx23885/cx23885-core.c:1146:2: warning: passing argument 1
of ‘videobuf_dma_unmap’ from
I can confirm that the current git HEAD (4419a4ff8) does not produce
this warning. Do you need further verification though?

To manage
I've only had access to 32-bit installs so far, with which this error
looks fairly innocuous (looks like the dev argument isn't used to
establish mappings on 32-bit). However, on 64-bit, it appears that the
incorrect dev pointer code causes an oops (specified in bug 659348).
I've put a call for
This bug is missing the SRU Justification text in the description or in
a comment, please update it.
Also it is awaiting verification that the kernel in -proposed solves the
problem. Please test the kernel and update this bug with the results. If
the problem is solved, change the tag

Just to clarify: bcbfc24 is a sauce patch that backports some IR stuff
from post-2.6.35. The cx23885-core changes must have snuck in
unintentionally.
