      V4L/DVB (5887): zr36067: Fix poll() operation · e42af83f
      Trent Piepho authored
      During uncompressed capture, the poll() function was looking the wrong frame.
      It was using the frame the driver was going to capture into next (pend_tail),
      when it should have been looking at the next frame to be de-queued with
      DQBUF/SYNC (sync_tail).
      
      It also wasn't looking in the right spot.  It was looking at the file handle's
      copy of the buffer status, rather than the driver core copy.  The interrupt
      routine marks frames as done in the driver core copy, the file handle copy
      isn't updated.  So even if poll() looked at the right frame, it would never
      see it transition to done and return POLLIN.
      
      The compressed capture code has this same problem, looking in fh->jpg_buffers
      when it should have used zr->jpg_buffers.
      
      There was some logic to detect when there was no current capture in process
      nor any frames queued and try to return an error, which ends up being a bad
      idea.  It's possible to call select() from one thread while no capture is in
      process, or no frames queued, and then start a capture or queue frames from
      another thread.
      
      The buffer state variables are protected by a spin lock, which the code wasn't
      acquiring.  That is fixed too.

      V4L/DVB (5886): zr36067: Fix problem setting norms · c812b67c
      Trent Piepho authored
      The zr36067 driver doesn't make a distinction between the different sub-types
      of NTSC, PAL, or SECAM norms.  For example, when the enum std ioctl returns
      the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I.
      
      When setting the norm, it required the bitmask to match exactly the set of
      norms used during the enumeration.  If just one norm was specified, for
      example PAL_BG or NTSC_M, it would fail.  This violates the V4L2 spec,
      "VIDIOC_S_STD accepts *one* or more flags..."
      
      The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple
      bits.  It's ok to call S_STD with any *one* of those bits, but the driver was
      requiring *all* of them.
      
      This fixes the S_STD function so that it will accept any set of one or more
      PAL norms as PAL, and the same for NTSC and SECAM.

      [SPARC64]: Fix conflicts in SBUS/PCI/EBUS/ISA DMA handling. · ad7ad57c
      David S. Miller authored
      Fully unify all of the DMA ops so that subordinate bus types to
      the DMA operation providers (such as ebus, isa, of_device) can
      work transparently.
      
      Basically, we just make sure that for every system device we
      create, the dev->archdata 'iommu' and 'stc' fields are filled
      in.
      
      Then we have two platform variants of the DMA ops, one for SUN4U which
      actually programs the real hardware, and one for SUN4V which makes
      hypervisor calls.
      
      This also fixes the crashes in parport_pc on sparc64, reported by
      Meelis Roos.

      [VIDEO]: Fix OOPS in all SBUS framebuffer drivers. · c7f439b9
      David S. Miller authored
      All of these drivers use a silly:
      
      struct all_info {
      	struct fb_info info;
      	struct foo_par par;
      };
      
      struct all_info *all = kzalloc(sizeof(*all), GFP_KERNEL);
      all->info.par = &all->par;
      
      etc. etc. code sequence, basically replicating the provided
      framebuffer_alloc()/framebuffer_release(), and doing it badly.
      
      Not only is this massive code duplication, it also caused a
      bug in that we weren't setting the fb_info->device pointer
      which results in an OOPS when fb_is_primary_device() runs.
      
      Fix all of this by using framebuffer_{alloc,release}() and
      passing in "&of_device->dev" as the device pointer.
