Since commit b4028437 the 'driver_data' field resides in device's struct device_private which may be allocated by dev_set_drvdata() if device_private struct was not allocated previously. dev_set_drvdata() is used in video_set_drvdata() to set the driver's private data pointer in v4l2 drivers. Setting the private data _before_ registering the v4l2 device results in a memory leak since __video_register_device() also calls video_set_drvdata(), but after zeroing the device structure. Thus, the reference to the previously allocated device_private struct goes lost and a new device_private will be allocated. All v4l drivers which call video_set_drvdata() _before_ calling video_register_device() are affected. The patch fixes __video_register_device() to preserve previously allocated device_private reference. Caught by kmemleak. Signed-off-by:

Started out as an effort to try to tackle the last remaining issue I'm having with this damned pinnacle device getting wedged the first time its plugged in after an indeterminate length of not being plugged in. Didn't get that solved yet, but did streamline the init code a bit more and remove some superfluous gunk. Nukes a completely unneeded call to usb_device_init() and several lines of overly complex crap in the gen1 device init path. Signed-off-by:

The UVCIOC_CTRL_MAP ioctl doesn't support menu entries for menu controls. As the uvc_xu_control_mapping structure has no reserved fields, this can't be fixed while keeping ABI compatibility. Modify the UVCIOC_CTRL_MAP ioctl to add menu entries support, and define UVCIOC_CTRL_MAP_OLD that supports the old ABI without any ability to add menu controls. Signed-off-by:

According to the v4l2 spec, writing any value to a button control should result in the action belonging to the button control being triggered. UVC cams however want to see a 1 written, this patch fixes this by overriding whatever value user space passed in with -1 (0xffffffff) when the control is a button control. Signed-off-by:

Per Pieter Hoekstra: I have a Antec Fusion with a iMON Lcd and I get the following error: imon 6-1:1.0: Unknown 0xffdc device, defaulting to VFD and iMON IR (id 0x9e) The driver is functional if I load it like this: (I do not use a remote for it) modprobe imon display_type=1 (On Mythbuntu 10.04/2.6.32) This device is a lcd-type with support for a MCE remote. Looking at the source code, this device (0x9e) is the same as id 0x9f. Signed-off-by:

It might be useful to be able to disable the IR support, either for debugging purposes, or just for users who know they won't use the IR remote control anyway. On many cards, IR support requires expensive polling/sampling which is better avoided if never needed. Signed-off-by:

Move I2C IR initialization from just after I2C bus setup to right before non-I2C IR initialization. This is the same as was done for the bttv driver several months ago. Might solve bugs which have not yet been reported for some cards. It makes both drivers consistent, and makes it easier to disable IR support (coming soon.) Signed-off-by:

Move from the generic, shared card_ir state structure to a cx23885 driver specific IR state structure in anticipation of moving to the new IR pulse decoders in the IR core. Fix up the card name truncation in the dmesg log while we're at it, by avoiding using fixed length string storage in our new IR state structure. Signed-off-by:

copy_to_user() returns the number of bytes remaining to be copied which isn't the right thing to return here. The comments say that these functions in dvb_ca_en50221.c should return the number of bytes copied or an error return. I've changed it to return -EFAULT. Signed-off-by:

Smatch complained because "d" is dereferenced first and then checked for null later . The only code path where "d" could be a invalid pointer is if this is a cold device in dvb_usb_device_init(). I consulted Antti Palosaari and he explained that anysee is always a warm device. I have added a comment and removed the unneeded null check. Signed-off-by:

Attached is the updated patch, please use this one instead. Thanks! Duplicate functionality with the gspca_zc3xx driver, zc0301 only supports 2 USB-ID's (because it only supports a limited set of sensors) wich are also supported by the gspca_zc3xx driver (which supports 53 USB-ID's in total).
