2008-01-25V4L/DVB (6545): em28xx: autodetect Cinergy 200 USB and VGear PocketTVSascha Sommer
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.

2008-01-25V4L/DVB (6538): em28xx: fix locking to allow accesses from 2 different ↵Sascha Sommer
threads at the same time 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>
2008-01-25V4L/DVB (6536): Add a hint for boards without unique USB IDMauro Carvalho Chehab
This patch adds a function to allow trying to detect boards that shares the generic IDs. The current detection method is based at eeprom checksum. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-01-25V4L/DVB (6384): Replace TDA9887_SET_CONFIG by TUNER_SET_CONFIGMauro Carvalho Chehab
Currently, the only tuner-specific device that allows special configurations is tda9887. However, tea5767 also may require some special configurations (for example, to specify a different Xtal freq). This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl (TUNER_SET_CONFIG). The newer one allows specifying what tuner is appliable to a configuration set, and allows an arbitrary configuration struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-11-04V4L/DVB (6514): em28xx: Include linux/mm.hTrent Piepho
This em28xx-video.c uses functions from this header, but doesn't include it. It depends on some v4l headers included two levels down including poll.h, which includes mm.h. These v4l headers might change, so it's best to include the headers needed directly. It also causes problems for the out of core build system's backward compatibility with older kernels, which is the real reason I bothered to create a patch for something that would otherwise be so minor that it would hardly be worth the trouble.

2007-10-22V4L/DVB (6320): v4l core: remove the unused .hardware V4L1 fieldMauro Carvalho Chehab
struct video_device used to define a .hardware field. While initialized on severl drivers, this field is never used inside V4L. However, drivers using it need to include the old V4L1 header. This seems to cause compilation troubles with some random configs. Better just to remove it from all drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-10V4L/DVB (6316): Change list_for_each+list_entry to list_for_each_entryTrent Piepho
The rest of V4L files. There is one list_for_each+list_entry in cpia_pp.c that wasn't changed because it expects the loop iterator to remain NULL if the list is empty. A bug in vivi is fixed; the 'safe' version needs to be used because the loop deletes the list entries. Simplify a second loop in vivi and get rid if an un-used variable in that loop.

2007-08-22USB: Fix a memory leak in em28xx_usb_probe()Jesper Juhl
If, in em28xx_usb_probe() the memory allocation dev->alt_max_pkt_size = kmalloc(32* dev->num_alt,GFP_KERNEL); fails, then we'll bail out and return -ENOMEM. The problem is that in that case we don't free the storage allocated to 'dev', thus causing a memory leak. This patch fixes the leak by freeing 'dev' before we return -ENOMEM.

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data.
