flags used for spinlocks don't need to be initialized, except where the compiler has no way to see, that the spin_unlock_irqrestore is only called if the spin_lock_irqsave has been called before. Local variable initialization doesn't have to be protected. Signed-off-by:

As reported by Roel Kluin <12o3l@tiscali.nl>: in drivers/media/radio/radio-sf16fmr2.c:319: for (i = 0; i < ARRAY_SIZE(radio_qctrl); i++) { if ((fmr2->card_type != 11) && V4L2_CID_AUDIO_VOLUME) radio_qctrl[i].step = 65535; ... I don't understand this '&& V4L2_CID_AUDIO_VOLUME' While fixing this issue, I've revisited the volume control code and fixed CodingStyle on the changed procedures. Signed-off-by: -

Make the dev member of the struct videobuf_queue of type "struct device *" to avoid future problems. Also change the prototype of the videobuf_queue_core_init() function. Signed-off-by:

tuner-xc2028 needs to know when a DVB module is sharing the same analog tuner. This is done by comparing a magic number that needs to be the same on analog and on digital. To make easier, this magic number is a pointer to some data struct. With the previous code, two different pointers were using, causing a miss-detection. Signed-off-by: -

I have what looks like a Geovision GV-600 (or 650) card. It has a large chip in the middle labeled CONEXANT FUSION 878A 25878-13 E345881.1 0312 TAIWAN It has an audio connector coming out from a chip labeled ATMEL 0242 AT89C2051-24PI It is identified as follows on my Debian GNU/Linux Etch (kernel 2.6.18) ... 01:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 01:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) ... 01:0a.0 0400: 109e:036e (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dfffe000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 01:0a.1 0480: 109e:0878 (rev 11) Subsystem: 008a:763c Flags: bus master, medium devsel, latency 64, IRQ 58 Memory at dffff000 (32-bit, prefetchable) [size=4K] Capabilities: [44] Vital Product Data Capabilities: [4c] Power Management version 2 It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18 kernel and the latest v4l-dvb drivers, but it did not work at all. The card has sixteen (16) BNC video inputs, four of them on the board itself and twelve on three daughter-cards. It has a single bt878 chip, no tuner and what looks like and audio input. After doing some research I managed to get only eight channels working by forcing card=125 and those DID NOT match channels 0-7 on the card, and no audio. Based on what was working for card=125, I added the card definition block, added a specific muxsel routine and got the card working fully with xawtv, where the sixteen channels show up as Composite0 to Composite15, matching the channel labels in the card and daughter-cards. I have made no efforts yet to get audio working, but would appreciate any pointers. Signed-off-by:Ernesto Hernández-Novich <emhn@usb.ve> Signed-off-by:

poll_one allocated on stack struct poll_wqueues which is pretty big structure (>500 bytes on x86_64). v4l1_compat_sync invokes poll_one in a loop, so allocate struct poll_wqueues in v4l1_compat_sync (with kmalloc) and pass it to poll_one. Signed-off-by:

simple_dvb_configure returns the actual tuned frequency to its caller, so it must be declared as a u32 rather than an int. As a result, we will return 0 to indicate a failure. Signed-off-by:

if (priv->i2c_props.adap == NULL) then exit any function that would send commands over the i2c bus. We allow drivers to attach without an i2c adapter for cases where the dvb demod accesses the tuner directly via calc_regs. Signed-off-by:

Convert tda9887 to use the new hybrid_tuner_request_state and hybrid_tuner_release_state macros to manage state sharing between hybrid tuner instances. Some ATSC/DVB cards need to put the analog demodulator into standby before tuning digital. This patch allows us to attach the tda9887 driver to the digital side of the bridge driver and be able to put it into standby without jeopardizing the analog demod driver's state. Signed-off-by:
