Unplugging a pwc cam while an app has the /dev/video# node open leads to an oops in pwc_video_close when the app closes the node, because the disconnect handler has free-ed the pdev struct pwc_video_close tries to use. Instead of adding some sort of bandaid for this. fix it properly using the v4l2 core's new(ish) behavior of keeping the v4l2_dev structure around until both unregister has been called, and all file handles referring to it have been closed: Embed the v4l2_dev structure in the pdev structure and define a v4l2 dev release callback releasing the pdev structure (and thus also the embedded v4l2 dev structure.

For now, the m5mols_read() share in case of I2C packet 1, 2, 4 byte(s) width. So, this commit adds 3 functions - m5mols_read_u8/u16/u32() according to byte width of I2C packet. And, the u32 variables in spite of u8 or u16 for fitting to m5mols_read() having no choice, is replaced to have original byte width like u8, u16, u32 as same reason. Signed-off-by:

The main capture and the thumbnail image size registers were erroneously defined to have 1 byte width, resulting in wrong reported image size. Fix this by changing the registers width to correct value. Reported-by:

Hans Petter Selasky pointed out to me that we're leaking urbs when mce_async_out is called. Its used both for configuring the hardware and for transmitting IR data. In the tx case, mce_request_packet actually allocates both a urb and the transfer buffer, neither of which was being torn down. Do that in the tx callback.

There was a missing lock in fintek_suspend. Without the lock, its possible the system will be in the middle of receiving IR (draining the RX buffer) when we try to disable CIR interrupts. Signed-off-by:

Store the cdev pointer in struct irctl, allocated dynamically as needed, rather than having a static array. At the same time, recycle some of the saved memory to nudge the maximum number of lirc devices supported up a ways -- its not that uncommon these days, now that we have the rc-core lirc bridge driver, to see a system with at least 4 raw IR receivers. (consider a mythtv backend with several video capture devices and the possible need for IR transmit hardware). Signed-off-by:

Aside from the initial "hey, lets make sure we've flushed any pre-existing data on the device" call to mce_sync_in, every other one of the calls was entirely superfluous. Ergo, remove them all, and rename the one and only (questionably) useful one to reflect what it really does. Verified on both gen2 and gen3 hardware to make zero difference. Well, except that you no longer get a bunch of urb submit failures from the unneeded mce_sync_in calls. Oh. And move that flush to a point *after* we've wired up the inbound urb, or it won't do squat. I have half a mind to just remove it entirely, but someone thought it was necessary at some point, and it doesn't seem to hurt, so lets leave it for the time being. This excercise took place due to insightful questions asked by Hans Petter Selasky, about the possible reuse of the inbound urb before it was actually availble by mce_sync_in, so thanks to him for motivating this cleanup.

The find_next_zero_bit() is called with the from and to arguments in the wrong order. This results in the function always returning 0, and all media devices being registered with minor 0. Furthermore, mdev->minor is then used before being assigned with the find_next_zero_bit() return value. This really makes sure we'll always use minor 0. Fix this and let the system support more than one media device. Signed-off-by:

Two ivtv_msleep_timeout() calls are incorrectly flagged as interruptable. The first is in the init sequence for a capture and is required for stable hardware setup. The second is at the end of the capture and used to handle the last data transfer. Failure to wait for this last transfer can result in stale data being read at the start of the next capture.
