2009-03-30V4L/DVB (10519): em28xx: Fix for em28xx audio startupRobert Krakora
Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion. It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.

2009-02-26V4L/DVB (10659): em28xx: register device to soundcard for sysfsNicola Soranzo
As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should set the struct device for the card before registering the card instance. This will add the correct /sys/class/sound/cardN/device symlink, so HAL can see the device and ConsoleKit sets its ACL permissions for the logged-in user. For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2), this patch fixes errors like: ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied when running mplayer as a normal user.

Since pre-emption is enabled then it is safe to de-allocate the memory if you first unlink each URB. In this instance you are safe since pre-emption is disabled. If pre-emption and irqs are not disabled then call usb_kill_urb(), else call usb_unlink_urb(). Thanks to Douglas for tracking down this bug originally!!!

instead of ID. Since the i2c driver ID will be removed in the near future we have to modify the v4l2 debugging API to use the driver name instead of driver ID. Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only.

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.

2008-12-30V4L/DVB (10130): use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_is_isoc_in(epd) usb_endpoint_is_isoc_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Correct problem introduced during the board refactoring where the XCLK frequency would get zero'd out. The sequence of events was as follows: em28xx_pre_card_setup() called em28xx_set_model() em28xx_set_model() would memcpy to dev->board configuration em28xx_pre_card_setup() would set the dev->board.xclk if not set em28xx_pre_card_setup() would set the XCLK register based on dev->board.xclk ... em28xx_card_setup() would call em28xx_set_model() em28xx_set_model() would memcpy to dev->board configuration (clearing out value of dev->board.xclk set in em28xx_pre_card_setup) ... em28xx_audio_analog_set() sets the XCLK register based on dev->board.xclk (which now contains zero) The change sets the default XCLK and I2C Clock fields in the board definition inside of em28xx_set_model() so that subsequent calls do not cause the values to be overwritten.
