As far as we know devices can either have audio class or vendor class usb interfaces but not both at the same time. Even if both interface types could be provided by devices at the same time, the current code is totally broken for that case. So clean up and simplify the usb audio class handling by replacing fields "has_audio_class" (device has usb audio class compliant interface) and "has_alsa_audio" (device has vendor audio interface) in struct em28xx with a single enum em28xx_usb_audio_type.

Fields "ac97_feat", "ac97_vendor_id" and "i2s_samplerates" of struct em28xx_audio_mode are used nowhere, except in function em28xx_audio_setup(). So get rid of them and use local variables instead. Signed-off-by:

This patch adds support for Si2147-A30 tuner. Fairly trivial, no firmware needed for this tuner. However, command 14 00 02 07 01 00 seems to be mandatory. On Si2157 and Si2158 the value 0x0100 is the default value, so this patch does not impact the existing tuners/devices. On Si2147 the default is 0x0000 and I can't get a lock with that value. While here, fix the return length of the previous set command to 4 bytes. Signed-off-by:

"program_info_length" is user controlled and can go up to 4095. The operand[] array has 509 bytes so we need to add a limit here to prevent buffer overflows. The " - 4" in the limit check is because we have 4 bytes more data to add after the memcpy(). [mchehab@osg.samsung.com: as I merged the version 1 of the patch, I needed to rebase to apply just the differences between v1 and v2] Signed-off-by:

mceusb_init_rc_dev() does usb_get_dev(), but there is no any usb_put_dev() in the driver. The patch tries to straighten logic. It moves usb_get_dev() directly to mceusb_dev_probe() and adds usb_put_dev() to an error path and to mceusb_dev_disconnect(). Found by Linux Driver Verification project (linuxtesting.org).

GIT_AUTHOR_DATE=1409603039 This reverts commit b99f0aad Author: Mauro Carvalho Chehab <m.chehab@samsung.com> [media] em28xx: check if a device has audio earlier Better to split chipset detection from the audio setup. So, move the detection code to em28xx_init_dev(). It broke analog audio of the Hauppauge winTV HVR 900 and very likely many other em28xx devices. Background: The local variable has_audio in em28xx_usb_probe() describes if the currently probed _usb_interface_ has an audio endpoint, while dev->audio_mode.has_audio means that the _device_ as a whole provides analog audio. Hence it is wrong to set dev->audio_mode.has_audio = has_audio in em28xx_usb_probe(). As result, audio support is no longer detected and configured on devices which have the audio endpoint on a separate interface, because em28xx_audio_setup() bails out immediately at the beginning. Revert the faulty commit to restore the old audio detection procedure, which checks the chip configuration register to determine if the device has analog audio.

Right now, the au0828 driver uses .tuner to detect if analog tv is being used or not. By not filling .tuner fields at the board struct, the I2C core can't do decisions based on it. So, add a field to explicitly tell when analog TV is supported. No functional changes. Signed-off-by: -

This comment is already at the au0828-i2c where it belongs. So, remove it from a board's entry. It doesn't make any sense there, as we're setting the clock to 250kHz there, slowing it down only at the au0828-i2c. Signed-off-by: -

Instead of using a temporary stack allocated i2c_client in em28xx_i2c_ir_handle_key(), allocate/free the i2c_client at module init/uninit and hook it into struct em28xx_IR (if the device has an i2c IR decoder). This reduces the frame size of function em28xx_i2c_ir_handle_key() and speeds it up a bit. Also make sure that all fields of struct i2c_client are initialized properly. Signed-off-by:

The norm_swidth function was unused and is dropped. It's not clear what the purpose of that function was. The norm_maxh function was changed so it tests for 60 Hz standards rather than for 50 Hz standards. The is the preferred order. The norm_maxw function was poorly written and used: it gives the maximum allowed line width for the given standard. For 60 Hz that's 720, but for 50 Hz that's 768 which allows for 768x576 which gives you square pixels. For 60 Hz formats it is 640x480 that gives square pixels, so there is no need to go beyond 720. The initial width was set using norm_maxh(), which was wrong. Just set to 720, that's what you normally use. Since the initial standard was NTSC anyway the initial width was always 720 anyway.

Both adv7604 and adv7842 had the same typo in the code that sets the vertical backporch for the second interlaced field: it was assigned to vbackporch instead of il_vbackporch. In addition, the timings struct wasn't zeroed in the adv7842 driver, leaving several fields to undefined values causing the timing match function to fail. Signed-off-by:

If one or both of the timings being compared have the standards field with value 0, then accept that. Only check for matching standards if both timings have actually filled in that field. Otherwise no match will ever be found since when timings are detected the standards field will typically be set to 0 by the driver. Signed-off-by:
