      [media] v4l: Support extending the v4l2_pix_format structure · d52e2381
      Laurent Pinchart 提交于
      The v4l2_pix_format structure has no reserved field. It is embedded in
      the v4l2_framebuffer structure which has no reserved fields either, and
      in the v4l2_format structure which has reserved fields that were not
      previously required to be zeroed out by applications.
      
      To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
      structure, and use the priv field as a magic value to indicate that the
      application has set all v4l2_pix_format extended fields and zeroed all
      reserved fields following the v4l2_pix_format field in the v4l2_format
      structure.
      
      The availability of this API extension is reported to userspace through
      the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
      priv field is still set to the magic value at [GS]_FMT return wouldn't
      be enough, as older kernels don't zero the priv field on return.
      
      To simplify the internal API towards drivers zero the extended fields
      and set the priv field to the magic value for applications not aware of
      the extensions.

      [media] Fix 64-bit division fall-out from 64-bit control ranges · 0d5e8c43
      Hans Verkuil 提交于
      Commit 0ba2aeb6 increased the internal control ranges
      to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value
      control values in a division or modulus operations since not all architectures support
      those natively.
      
      Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
      is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
      use do_div in one function.

      [media] dib8000: export just one symbol · d44913c1
      Mauro Carvalho Chehab 提交于
      Exporting multiple symbols don't work as it causes compilation
      breakages, due to the way dvb_attach() works.
      
      The bug happens when:
              CONFIG_DVB_DIB8000=m
      	CONFIG_DVB_USB_DIB0700=y
      
      As a bonus, dib8000 won't be loaded anymore if the device uses
      a different frontend, reducing the memory footprint.
      
      Tested with both Pixelview PV-D231 and MyGica S870.
