We've got a bug report at disconnecting a Webcam, where the kernel spews warnings like below: WARNING: CPU: 0 PID: 8385 at ../fs/sysfs/group.c:219 sysfs_remove_group+0x87/0x90() sysfs group c0b2350c not found for kobject 'event3' CPU: 0 PID: 8385 Comm: queue2:src Not tainted 3.16.2-1.gdcee397-default #1 Hardware name: ASUSTeK Computer INC.

The fix is simply rearrange the call orders in uvc_delete() so that the child is removed before the parent.

Several control helper functions are no longer needed since most drivers are now converted to the control framework. So we can delete them. Signed-off-by:

Never use sg++, always use sg = sg_next(sg). Scatterlist entries can be combined if the memory is contiguous but sg++ won't know about that. As far as I can tell cx88 and ivtv are really broken because of this, and bttv and cx25821 are OK because vb1 doesn't combine scatterlist entries. But regardless, sg++ should never be used, only sg_next is safe. Signed-off-by:

In smipcie.c, the function i2c_bit_add_bus() is called. This function is defined by the I2C bit-banging interfaces enabled with CONFIG_I2C_ALGOBIT. As there was no dependency in Kconfig, CONFIG_I2C_ALGOBIT could be set to "m" while CONFIG_DVB_SMIPCIE was set to "y", resulting in a build error due to an undefined reference. This patch adds the dependency on CONFIG_I2C_ALGOBIT in Kconfig by selecting it when CONFIG_DVB_SMIPCIE is selected. Signed-off-by:

There is RTL2832P devices having extra MN88473 demodulator. This patch add support for such configuration. Logically MN88473 slave demodulator is connected to RTL2832 master demodulator, both I2C bus and TS input. RTL2832 is integrated to RTL2832U and RTL2832P chips. Chip version RTL2832P has extra TS interface for connecting slave demodulator. Signed-off-by:

The omap2 camera driver and the tcm825x sensor driver have been deprecated for a year and are now being removed. They are unmaintained and they use an internal API that has long since been superseded by a much better API. Worse, that internal API has been abused by out-of-kernel trees (i.MX6). In addition, Sakari stated that these drivers have never been in a usable state in the mainline kernel due to missing platform data. Signed-off-by:

Add device tree support by changing the device registration order. In the device tree the si4713 node is a normal I2C device, which will be probed as such. Thus the V4L device must be probed from the I2C device and not the other way around. Signed-off-by:
