V4L: buf_qbuf: fix videobuf_queue->stream corruption and lockup

2007-02-23T23:49:52+00:00

We are doing ->buf_prepare(buf) before adding buf to q->stream list. This means that videobuf_qbuf() should not try to re-add a STATE_PREPARED buffer.

V4L: Fix quickcam communicator driver for big endian architectures

2007-02-23T23:49:52+00:00

Host endianess does not affect the order that pixel rgb data comes in from the quickcam (the values are bytes, not words or longs). The driver is erroniously swapping the order of rgb values for big endian machines. This patch is needed get the Quickcam communicator working on big endian machines (tested on powerpc) (cherry picked from commit c6d704c8c4453f05717ba88792f70f8babf95268) Signed-off-by: Grant Likely Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Michael Krufky Signed-off-by: Greg Kroah-Hartman

dvb-core: fix bug in CRC-32 checking on 64-bit systems

2007-02-23T23:49:51+00:00

CRC-32 checking during ULE decapsulation always failed on x86_64 systems due to the size of a variable used to store CRC. This bug was discovered on Fedora Core 6 with kernel-2.6.18-1.2849. The i386 counterpart has no such problem. This patch has been tested on 64-bit system as well as 32-bit system.

[PATCH] V4L: Fix broken TUNER_LG_NTSC_TAPE radio support

2006-12-17T00:20:47+00:00

The TUNER_LG_NTSC_TAPE is identical in all respects to the TUNER_PHILIPS_FM1236_MK3. So use the params struct for the Philips tuner. Also add this LG_NTSC_TAPE tuner to the switches where radio specific parameters are set so it behaves like a TUNER_PHILIPS_FM1236_MK3. This change fixes the radio support for this tuner (the wrong bandswitch byte was used). Thanks to Andy Walls for finding this bug.

[PATCH] DVB: lgdt330x: fix signal / lock status detection bug

2006-12-17T00:20:47+00:00

In some cases when using VSB, the AGC status register has been known to falsely report "no signal" when in fact there is a carrier lock. The datasheet labels these status flags as QAM only, yet the lgdt330x module is using these flags for both QAM and VSB. This patch allows for the carrier recovery lock status register to be tested, even if the agc signal status register falsely reports no signal. Thanks to jcrews from #linuxtv in irc, for initially reporting this bug. Signed-off-by: Michael Krufky Signed-off-by: Chris Wright

[PATCH] DVB: fix dvb_pll_attach for mt352/zl10353 in cx88-dvb, and nxt200x

2006-11-04T01:33:46+00:00

DVB: fix dvb_pll_attach for mt352/zl10353 in cx88-dvb, and nxt200x Typical wiring of MT352, ZL10353, NXT2002 and NXT2004 based tuners differ from dvb-pll's expectation that the PLL is directly accessible. On these boards, the PLL is actually hidden behind the demodulator, and as such can only be accessed via the demodulator's interface. It was failing to communicate with the PLL during an attach test and subsequently not connecting the tuner ops. By passing a NULL I2C bus handle to dvb_pll_attach, this accessibility check can be bypassed. Do this for the affected boards. Also fix a possible NULL dereference at sleep time, which would otherwise be exposed by this change. This patch has been backported to the 2.6.18.y stable kernel series from the original changesets from Chris Pascoe and Michael Krufky, already present in the upstream 2.6.19 kernel tree.
