When the usb device is disconnected, the resources are no longer available, so there is no reason to keep them registered. This will also fix the various sysfs group removal warnings which we can see since kernel 3.13. Signed-off-by:

[media] em28xx-v4l: move v4l2_ctrl_handler freeing and v4l2_device unregistration to em28xx_v4l2_fini v4l2_ctrl_handler_free() and v4l2_device_unregister() are currently only called when the last user closes the device and the device is already disconnected. But that's wrong, we need to call these functions whenever the em28xx-v4l extension is closed and we can already do this if the device is still opened by some users. Signed-off-by:

s5p_mfc_get_node_type() relies on get_index() helper function, which in turn relies on video_device index numbers assigned on driver registration. All this code is not really needed, because there is already access to respective video_device structures via common s5p_mfc_dev structure. This fixes the issues introduced by patch 1056e438 ("v4l2-dev: Fix race condition on __video_register_device"), which has been merged in v3.12-rc1. Signed-off-by:

The URB calculus code may eventually be moved to some other place, like at pcm open, if it ends by needing more setups, like working with different bit rates, or different audio latency. So, move it into a separate routine. That also makes the code more readable. No functional changes. Signed-off-by: -

Pulseaudio has the bad habit of stopping a streaming audio if a device, opened in non-block mode, waits. It is impossible to avoid em28xx to wait, as it will send commands via I2C, and other I2C operations may be happening (firmware transfers, Remote Controller polling, etc). Yet, as each em28xx subdriver locks em28xx-dev to protect the access to the hardware, it is possible to minimize the audio glitches by returning -EAGAIN to pulseaudio, if the lock is already taken by another subdriver.

If the period size is wrong, userspace will assume a wrong delay any may negociate an inadequate value. The em28xx devices use 8 for URB interval, in microframes, and the driver programs it to have 64 packets. That means that the IRQ sampling period is 125 * 8 * 64, with is equal to 64 ms. So, that's the minimal latency with the current settings. It is possible to program a lower latency, by using less than 64 packets, but that increases the amount of bandwitdh used, and the number of IRQ events per second. In any case, in order to support it, the driver logic should be changed to fill those parameters in realtime. Signed-off-by: -

The current code hardcodes the number of audio URBs, the number of packets per URB and the maximum URB size. This is not a good idea, as it: - wastes more bandwidth than necessary, by using a very large number of packets; - those constants are bound to an specific scenario, with a bandwidth of 48 kHz; - don't take the maximum endpoint size into account; - with urb->interval = 1 on xHCI, those constraints cause a "funny" setup: URBs with 64 packets inside, with only 24 bytes total. E. g. a complete waste of space. Change the code to do dynamic URB audio calculus and allocation. For now, use the same constraints as used before this patch, to avoid regressions. A good scenario (tested) seems to use those defines, instead: #define EM28XX_MAX_AUDIO_BUFS 8 #define EM28XX_MIN_AUDIO_PACKETS 2 But let's not do such change here, letting the optimization to happen on latter patches, after more tests.

Just filling urb->interval with 1 is wrong, and causes a different behaviour with xHCI. With EHCI, the URB size is typically 192 bytes. However, as xHCI specifies intervals in microframes, the URB size becomes too short (24 bytes). With this patch, the interval will be properly initialized, and the device will behave the same if connected into a xHCI or an EHCI device port. Signed-off-by: -

If i2c_debug is enabled, we splicitly want to know when a device fails with timeout. If i2c_debug==2, this is already provided, for each I2C transfer that fails. However, most of the time, we don't need to go that far. We just want to know that I2C transfers fail. So, add such errors for normal (ret == 0x10) I2C aborted timeouts. Signed-off-by: -

The I2C output messages is too polluted. Clean it a little bit, by: - use the proper core support for memory dumps; - hide most stuff under the i2c_debug umbrella; - add the missing KERN_CONT where needed; - use 2 levels or verbosity. Only the second one will show the I2C transfer data. Signed-off-by: -

Follow the error codes for I2C as described at Documentation/i2c/fault-codes. In the case of the I2C status register (0x05), this is mapped into: - ENXIO - when reg 05 returns 0x10 - ETIMEDOUT - when the device is not temporarily not responding (e. g. reg 05 returning something not 0x10 or 0x00) - EIO - for generic I/O errors that don't fit into the above. In the specific case of 0-byte reads, used only during I2C device probing, it keeps returning -ENODEV. TODO: return EBUSY when reg 05 returns 0x20 on em2874 and upper. Signed-off-by:

In the lack of a better spec, let's assume the timeout values compatible with SMBus spec: http://smbus.org/specs/smbus110.pdf at chapter 8 - Electrical Characteristics of SMBus devices Ok, SMBus is a subset of I2C, and not all devices will be following it, but the timeout value before this patch was not even following the spec. So, while we don't have a better guess for it, use 35 + 1 ms as the timeout. Signed-off-by:
