This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it's type-safe and much easier to read. Found by coccinelle. Hand patched and reviewed. Tested by compilation only. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // </smpl> Signed-off-by:

I've always found it very confusing that the "Media ancillary drivers (tuners, sensors, i2c, frontends)" comment came after the "Autoselect" option. This patch moves it up and changes the "Autoselect" text to correspond more closely to the "Media ancillary drivers" comment. It also fixes two typos. Signed-off-by:

When the bttv driver is running without i2c_debug being set, the kernel log is being flooded with the string ">". This string is really a part of a debug message that is logged using several substrings protected by a conditional check. This patch adds the same conditional check to the leaked substring.

During modiles initialization rc-core schedules work which calls request_module() several times to load ir-*-decoder modules, but it does not wait or cancel this work on module unloading. rc-core should use request_module_nowait() instead, because it anyway cannot load modules synchronously or cancel/wait pending work on unloading, because this leads to deadlock on modules_mutex between several "modprobe" processes.

Use uninterruptible mutex_lock in the release() file op to make sure all resources are properly freed when a process is being terminated. Returning -ERESTARTSYS has no effect for a terminating process and this may cause driver resources not to be released.

The SAA7134 appears to have trouble buffering more than one line of video when doing DMA. Rather than try to fix the driver to cope (as has been done by Andy Walls for the cx18 driver), put in a pm_qos_request to limit deep sleep exit latencies. The visible effect of not having this is that seemingly random lines are only partly transferred - if you feed in a static image, you see a portion of the image "flicker" into place.

Since most dvb ioctls wrap their real work with dvb_usercopy, the static mutex used in dvb_usercopy effectively is a global lock for dvb ioctls. Unfortunately, frontend ioctls can be blocked by the frontend thread for several seconds; this leads to unacceptable lock contention. Mitigate that by pushing the mutex from dvb_usercopy down to the individual, device specific ioctls. There are 10 such ioctl functions using dvb_usercopy, either calling it directly, or via the trivial wrapper dvb_generic_ioctl. The following already employ their own locking and look safe: • dvb_demux_ioctl (as per dvb_demux_do_ioctl) • dvb_dvr_ioctl (as per dvb_dvr_do_ioctl) • dvb_osd_ioctl (as per single non-trivial callee) • fdtv_ca_ioctl (as per callees) • dvb_frontend_ioctl The following functions do not, and are thus changed to use a device specific mutex: • dvb_net_ioctl (as per dvb_net_do_ioctl) • dvb_ca_en50221_io_ioctl (as per dvb_ca_en50221_io_do_ioctl) • dvb_video_ioctl • dvb_audio_ioctl • dvb_ca_ioctl Signed-off-by:Nikolaus Schulz <schulz@macnetix.de> Signed-off-by:

That likely fixes this MythTV ticket: http://code.mythtv.org/trac/ticket/10830 (which btw affects all usb tuners I tested as well, pctv452e, dib0700, af9015) pctv452e is still possibly broken with MythTV even after this fix; it does work with VDR here tho despite I2C errors.

I was testing my video-over-ethernet subsystem recently, and vivi seemed to be perfect video source for testing when one don't have lots of capture boards and cameras. Only its framerate was hardcoded to NTSC's 30fps, while in my country we usually use PAL (25 fps) and I needed that to precisely simulate bandwidth. That's why here is this patch with ->enum_frameintervals() and ->{g,s}_parm() implemented as suggested by Hans Verkuil which passes v4l2-compliance and manual testing through v4l2-ctl -P / -p <fps>. Regarding newly introduced __get_format(u32 pixelformat) I decided not to convert original get_format() to operate on fourcc codes, since >= 3 places in driver need to deal with v4l2_format and otherwise it won't be handy.
