ALSA: usb: caiaq: audio: don't print error when allocating urb fails

2016-08-11T21:05:57+00:00

kmalloc will print enough information in case of failure. Signed-off-by: Wolfram Sang Signed-off-by: Takashi Iwai

ALSA: snd-usb-caiaq: fix stream count check

2015-01-05T07:56:19+00:00

Commit 897c329bc ("ALSA: usb: caiaq: check for cdev->n_streams > 1") introduced a safety check to protect against bogus data provided by devices. However, the n_streams variable is already divided by CHANNELS_PER_STREAM, so the correct check is 'n_streams > 0'. Fix this to un-break support for stereo devices.

ALSA: usb: caiaq: check for cdev->n_streams > 1

2014-10-07T12:34:25+00:00

Coverity spotted a possible DIV0 condition when cdev->n_streams is 0. Fix this by making sure the value is > 1 in snd_usb_caiaq_audio_init(). Signed-off-by: Daniel Mack Signed-off-by: Takashi Iwai

ALSA: snd-usb-caiaq: Fix LED commands for Kore controller

2014-09-22T06:52:14+00:00

KoreController and KoreController2 need an EP1_CMD_DIMM_LEDS command to set their LEDs, not EP1_CMD_WRITE_IO. Signed-off-by: Daniel Mack Reported-and-tested-by: Brad Wilson Signed-off-by: Takashi Iwai

ALSA: usb: Convert to snd_card_new() with a device pointer

2014-02-12T10:18:00+00:00

Also remove superfluous snd_card_set_dev() calls. Signed-off-by: Takashi Iwai

ALSA: snd-usb-caiaq: LED support for Maschine Controller

2013-09-30T09:19:16+00:00

This patch adds LED support for the Native Instruments Maschine Controller. It adds ALSA controls for dimming the LEDs of all buttons and the backlight of the two displays. Signed-off-by: Hannes Gräuler Acked-by: Daniel Mack Signed-off-by: Takashi Iwai

ALSA: usb: uniform style used in MODULE_SUPPORTED_DEVICE()

2013-06-21T12:37:08+00:00

In sound/usb/card.c and sound/usb/misc/ua101.c there are no spaces between the vendor and the device names, use this style in the other drivers too. This also helps keeping consistency when new drivers copies from the ones already in the mainline tree. Signed-off-by: Antonio Ospite Signed-off-by: Takashi Iwai

ALSA: snd-usb-caiaq: use vmalloc buffers

2013-06-21T12:35:52+00:00

For USB devices it's not necessary to allocate physically contiguous buffers. Signed-off-by: Antonio Ospite Signed-off-by: Takashi Iwai

ALSA: snd-usb-caiaq: remove the unused snd_card_used variable

2013-06-21T12:33:05+00:00

The snd_card_used variable is only read but never written, remove it. Signed-off-by: Antonio Ospite Signed-off-by: Takashi Iwai

ALSA: usb-audio: caiaq: fix endianness bug in snd_usb_caiaq_maschine_dispatch

2013-04-30T07:19:02+00:00

Current code does this: be16_to_cpu(buf[i * 2] << 8 | buf[(i * 2) + 1]) Which is effectively (neglecting the index): be16_to_cpu(be16_to_cpu(*((u16 *) buf))) This means the int16 in the buffer is not converted at all. Daniel Mack confirmed that the driver works on little endian CPUs, leading to the conclusion that the device-side structure is actually little endian. This changes the code to use le16_to_cpu(). Caught by sparse. Acked-by: Daniel Mack Signed-off-by: Eldad Zack Signed-off-by: Takashi Iwai
