2007-11-11Fix em28xx read stream lockingMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> On some situations, closing an streaming application and re-opening were returning -EBUSY. Uses the same locking schema also present on cx88. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-11-10Fix em28xx to allow multiple openMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Allows shared access support for em28xx. Just one userspace application is allowed to get stream. The other(s) application(s) can change V4L2 controls, set video standards, etc. This patch were splited from Markus Rechberger's tree and backported to 2.6.17 by Pádraig Brady. The original patch were ported to the latest em28xx version and had CodingStyle corrected to solve the issues pointed by scripts/checkpatch.pl.

2007-11-13V4L: Convert videobuf drivers to videobuf_stopBrandon Philips

2007-11-13V4L: videobuf-core locking fixes and commentsBrandon Philips
- Add comments to functions that require that caller hold q->lock - Add __videobuf_mmap_free that doesn't hold q->lock for use within videobuf - Add locking to videobuf_mmap_free - Fix linux/drivers/media/common/saa7146_video.c which was holding lock around videobuf_read_stop - Add locking to functions that operate on a queue - Add videobuf_stop to take care of stopping in both the read and stream case TODO: bttv still has an unsafe call to videobuf_queue_is_busy Signed-off-by: Brandon Philips <bphilips@suse.de>

From: Michael Krufky <mkrufky@linuxtv.org> To ensure prevention of detecting a tda9885/6/7 as a tda8290 or tda8295, we will rule out the tda988x before testing the tda8290 / tda8295 id registers. We read 8 bytes from the chip. If they are all equal, then it is not a tda829x, or some other error has occurred. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org>

From: Sascha Sommer <saschasommer@freenet.de> Adds autodetection support for the Cinergy200 USB and the VGear PocketTV. Whenever a usb device with generic empia em2800 usb ids is detected the device gets scanned for connected i2c devices. If the device list matches an em2800 device in the device list the model id gets changed accordingly.

2007-11-03 em28xx: add support for vgear pockettvMauro Carvalho Chehab
From: Sascha Sommer <saschasommer@freenet.de> attached patch adds support for the vgear pockettv. It seems to require a write to another register for audio to work. I checked my old cinergydrv and we did the same register write there. I therefore enabled it for all em2800 based devices.

2007-11-03em28xx: fix locking to allow accesses from 2 different threads at the same timeMauro Carvalho Chehab
From: Sascha Sommer <saschasommer@freenet.de> The attached patch modifies the em28xx driver so that there can be ioctls from multiple different threads. This is necessary for capture apps like MPlayer that use different threads for capturing and channel tuning. Now the locking is only done for the ioctls that change properties of the device or access the i2c bus. It also removes some locks that look unnecessary: In em28xx_init_dev: the videodevice is not registered yet so nothing can access the hardware meanwhile, the device struct is not assigned to the interface yet so no race with disconnect is possible In em28xx_release_resources: it gets only called when dev->lock is already held Signed-off-by: Sascha Sommer <saschasommer@freenet.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-11-02pvrusb2: Fix oops on module removalMike Isely
From: Mike Isely <isely@pobox.com> The pvrusb2 driver is tearing down its sysfs related pieces in the incorrect order. This leaves dangling pointers which causes the kernel device core to oops. The problem has been present virtually forever but became malignant with the changeover to the way of handling /sys/class. Fix is just to make sure we don't tear down the class structure until AFTER the driver instances are deregistered. Signed-off-by: Mike Isely <isely@pobox.com>
