2009-04-28au0828: fix kernel oops regression on USB disconnect.Devin Heitmueller
From: Devin Heitmueller <dheitmueller@linuxtv.org> A regression was introduced in hg changeset 33810c734a0d, which resulted in a kernel panic whenever the device was disconnected from USB. The call to 4l2_device_register() was overwriting the pointer for usb_set_intfdata(), so when au0828_usb_disconnect() was called, the usb_get_intfdata() returned a pointer to the v4l2_device instead of the au0828_dev structure.

2009-04-18uvcvideo: fix uvc resume failedtom.leiming@gmail.com
From: Ming Lei <tom.leiming@gmail.com> Now urb buffers is not freed before suspend, so uvc_alloc_urb_buffers should return packet counts allocated originally during uvc resume, instead of zero. This version uses round down to return packet counts on Linus' suggestions, or else may lead to buffer destructed if packet size is changed before calling uvc_alloc_urb_buffers() in this kind of case.

From: Márton Németh <nm127@freemail.hu> When querying menu items with VIDIOC_QUERYMENU the reserved field is not set to zero as required by V4L2 API revision 0.24 [1]. Add this fill.

2009-04-15uvcvideo: Prevent invormation loss with removing implicit castingLaurent Pinchart
From: Márton Németh <nm127@freemail.hu> The uvcvideo driver supports only one input, which is input 0. For all other input index the return value shall be EINVAL. This patch fixes the problem when the value 0x80000000 was incorrectly casted and treated as a zero value. The patch was tested with v4l-test 0.10 [2] with CNF7129 webcam found on EeePC 901.

From: Mauro Carvalho Chehab <mchehab@redhat.com> kernel-sync: Author: Alexey Dobriyan <adobriyan@gmail.com> Date: Wed Mar 25 22:48:06 2009 +0300 proc 2/2: remove struct proc_dir_entry::owner Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it.
