The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature. Signed-off-by:

If the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by:

It is not clear how to share the unlock in the case where the structure containing the lock has to be freed. So the unlock is now duplicated, with one copy moved before the free. The unlock label furthermore is no longer useful and is thus deleted. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; identifier f; iterator I; statement S; @@ *kfree(x); ... when != &x when != x = e when != I(x,...) S *x->f // </smpl> Signed-off-by:

Make the VBI support work for PAL standards in addition to NTSC. This work was sponsored by EyeMagnet Limited. Thanks go out to Andy Walls for providing a CD containing test PAL/VBI captures and to Steven Toth for providing a PVR-350 to do signal generation with. Signed-off-by:

When firmware 1.20 was introduced, the dib0700 switched from a polling model using a USB control message, to the messages being delivered on a USB bulk pipe. The code I originally added would do a blocking read on the pipe with a 50ms timeout. Because the dvb-usb-remote code makes use of the global workqueue, this resulted in the global workqueue being blocked 50% of the time. Also, the synchronous urb_bulk_msg() call would burn excess CPU time (reflected as an abnormal increase in the system's load average when devices were connected). Rework the logic so that we now setup an asynchronous callback on the bulk pipe, so that we now only handle RC data when it arrives on the pipe. Note that we provide a stub function for the RC polling callback so that we can continue to leverage the shared code in dvb-usb-rc for the setting up of the input device. Signed-off-by:

This change fixes up saa7127_s_std() generate SECAM out, if the user has requested a 50 Hz video standard set that only contains a request for SECAM standards and not PAL. Only the SAA712[89] chips can generate SECAM, the SAA712[67] chips cannot. I was unclear on the burst start and end values - I couldn't figure out the units - so I left them the same as for the PAL systems. A the video decoders on both a PVR-350 (SAA7115) and an HVR-1600 (CX23418) identify the SECAM signal generated by a SAA7129 with this patch as SECAM. Signed-off-by:

Fix the "xceive_pin" setting from "15" to "1" for the PVR2100 -- the same as the PVR3100H. This properly resets the XC2028 tuner on the PVR2100. Sergey's original email report: Hi. Seems cx18 module has incorrect .xceive_pin value for card, as i see lots of i2c errors in dmesg from xc2028. i'm using 2.6.32.2, my hardware is: 00:09.0 Multimedia video controller [0400]: Conexant Systems, Inc.

The CX18_CPU_SET_INDEXTABLE command was being called with the wrong number of arguments causing the index table frame type selection mask to be set wrong. Now the IDX stream properly sends entries for I, P, and B frames. Signed-off-by:

VIDIOC_G_ENC_INDEX support see the light of day. Some notes: 1. With default capture parameters, the CX23418 seems to transfer 192 index entries (4.5 kB worth) at 10 second intervals. 2. Index streams don't seem to be supported for MPEG 2 TS streams 3. The index entries seem to claim every frame is a B-Frame. Possible firmware bug. 4. The cx18 driver does not try to capture an index stream when inserting sliced VBI into the MPEg stream as the offsets would need fixup. Signed-off-by:

According to the v4l2 spec, very old MPEG index entries needs to be discarded in favor of newer index entries. This change ensures the firmware always has buffers for index entries at the expense of the oldest unread buffers. Signed-off-by:

This change starts the IDX stream along with the MPG stream as an internal use (only) stream much like the VBI stream can be started as an internal use stream for inserting sliced VBI packets. The IDX stream is not started automatically with an MPEG strem if the IDX stream is disabled (no buffers allocated) or if sliced VBI insertion is being performed by the cx18 driver. The cx18 driver doing sliced VBI insertion makes the offsets in the IDX stream inaccurate for the final MPEG stream presented to user space. Since fixing the IDX offsets ourselves is not easy and we cannot easily do what ivtv does to fix the offsets, we'll make sliced VBI insertion and MPEG Index capture mutually exclusive for now.

This change allows the IDX stream to be started and stopped as any other stream even though it has no associated device node. This is needed for cx18 driver internal use. Also always tell the CX23418 to generate index entries when an analog capture starts and the IDX stream has had buffers allocated (i.e. is enabled). Signed-off-by:

Update the module options related to INDEX stream buffer allocation. A single CX2341[5678] index entry is only 24 bytes. Large buffers for the IDX stream will prevent the CX23418 from transferring index data over at all. Buffers of around 1.5 kB or 64 index entries seem to be just fine. We'll default to 63 buffers/MDLs as that is the firmware limit per stream and IDX stream buffers are not high rate. There is no reason on earth to allocate the previous 1 MB default of buffer space for the IDX stream. This is in anticipation of implementing the G_ENC_INDEX ioctl() in the cx18 driver.
