2009-04-21gspca - main: Fix a crash when no bandwidth available.Jean-Francois Moine
From: Jean-Francois Moine <moinejf@free.fr> When the bandwidth is not wide enough, the transfer endpoint may be set to the one of the alternate setting 0. This one may be null and this causes a divide by 0 oops. Reported-by: Hans de Goede <hdegoede@redhat.com> Priority: normal Signed-off-by: Jean-Francois Moine <moinejf@free.fr>

2009-03-28gspca: Stop setting buffer type, and avoid memset in querycapTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The v4l2-ioctl core checks the buffer type now by only allowing buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined. This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE buffers are allowed to be used with vidioc_g_parm. Also, ->vidioc_enum_fmt_vid_cap() is only called for VIDEO_CAPTURE buffers. There is no need to set the buffer type since it must already be the correct value. The struct which ->vidioc_querycap() is supposed to fill in is already zeroed so it's not necessary to call memset on it.

2009-03-03gspca: Don't need to zero ioctl parameter fieldsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The v4l2 core code in v4l2_ioctl will zero out the structure the driver is supposed to fill in for read-only ioctls. For read/write ioctls, all the fields which aren't supplied from userspace will be zeroed out. Zeroing code is removed from g_audio, enum_input, g_parm and gmbuf.

2009-02-04gspca - main: Destroy the URBs at disconnection time.Jean-Francois Moine
From: Adam Baker <linux@baker-net.org.uk> If a device using the gspca framework is unplugged while it is still streaming then the call that is used to free the URBs that have been allocated occurs after the pointer it uses becomes invalid at the end of gspca_disconnect. Make another cleanup call in gspca_disconnect while the pointer is still valid (multiple calls are OK as destroy_urbs checks for pointers already being NULL.

2008-12-30v4l2: introduce v4l2_file_operations.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.
