ALSA: usb-audio: work around corrupted TEAC UD-H01 feedback data

2014-05-02T16:21:55Z

The TEAC UD-H01 firmware sends wrong feedback frequency values, thus causing the PC to send the samples at a wrong rate, which results in clicks and crackles in the output. Add a workaround to detect and fix the corruption.

ALSA: usb-audio: Fix deadlocks at resuming

2014-05-02T16:17:06Z

The recent addition of the USB audio mixer suspend/resume may lead to deadlocks when the driver tries to call usb_autopm_get_interface() recursively, since the function tries to sync with the finish of the other calls. For avoiding it, introduce a flag indicating the resume operation and avoids the recursive usb_autopm_get_interface() calls during the resume.

ALSA: usb-audio: Save mixer status only once at suspend

2014-05-02T16:14:42Z

The suspend callback of usb-audio driver may be called multiple times per suspend when multiple USB interfaces are bound to a single sound card instance. In such a case, it's superfluous to save the mixer values multiple times. This patch fixes it by checking the counter. Signed-off-by: Takashi Iwai

ALSA: usb-audio: Prevent printk ratelimiting from spamming kernel log while DEBUG not defined

2014-05-02T16:10:59Z

This (widely used) construction: if(printk_ratelimit()) dev_dbg() Causes the ratelimiting to spam the kernel log with the "callbacks suppressed" message below, even while the dev_dbg it is supposed to rate limit wouldn't print anything because DEBUG is not defined for this device. [ 533.803964] retire_playback_urb: 852 callbacks suppressed [ 538.807930] retire_playback_urb: 852 callbacks suppressed [ 543.811897] retire_playback_urb: 852 callbacks suppressed [ 548.815745] retire_playback_urb: 852 callbacks suppressed [ 553.819826] retire_playback_urb: 852 callbacks suppressed So use dev_dbg_ratelimited() instead of this construction.

BugLink: http://bugs.launchpad.net/bugs/1305133 Malfunctioning or slow devices can cause a flood of dmesg SPAM.

Merge tag 'asoc-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

2014-03-13T08:53:25Z

ASoC: Updates for v3.15 Quite a busy release for ASoC this time, more on janitorial work than exciting new features but welcome nontheless: - Lots of cleanups from Takashi for enumerations; the original API for these was error prone so he's refactored lots of code to use more modern APIs which avoid issues. - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle. - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues. - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues. - DPCM support for Intel Haswell and Bay Trail platforms. - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC.

This merges the bunch of changes over pci and usb sound drivers to convert to dev_err() and co.

ALSA: usb-audio: Use standard printk helpers

2014-02-26T15:45:34Z

Convert with dev_err() and co from snd_printk(), etc. As there are too deep indirections (e.g. ep->chip->dev->dev), a few new local macros, usb_audio_err() & co, are introduced. Also, the device numbers in some messages are dropped, as they are shown in the prefix automatically. Signed-off-by: Takashi Iwai
