2011-06-22ARM: tegra: Enable cdev1 clk from board fileSumit Bhattacharya
Enabling cdev1 clk or DAP Mclk from board file instead of codec soc file because Mclk needs to be enabled before codec initialization. Also exposing set_parent() for cdev clocks so that it is possible to enable them from board file.

2011-04-13ASOC: TEGRA: Make alsa more configurableSumit Bhattacharya
This change mainly takes care of following things: 1) Codec_dai code will use dap apis to query the board specific dap tables to find the codec configuration needed for a particular routing and will configure codec accordingly. So long we were configuring codec hardcodedly. 2) Moved all codec and board specific routing codes to codec specific files from tegra_soc_controls.c. 3) Modifying the codec routing logic to make it simpler and robust. 4) Except DAP Mclk we will turn off all other audio related clocks when not in use. 5) I2s and SPDIF bit clock frequencies will be dynamically calculated based on the stream properties. 6) DAS power management and DAP MCLK related codes are moved to codec dai since they are more closely related to codec than i2s.

2011-01-07sound: Prevent buffer overflow in OSS load_mixer_volumesDan Rosenberg
commit d81a12bc29ae4038770e05dce4ab7f26fd5880fb upstream. The load_mixer_volumes() function, which can be triggered by unprivileged users via the SOUND_MIXER_SETLEVELS ioctl, is vulnerable to a buffer overflow. Because the provided "name" argument isn't guaranteed to be NULL terminated at the expected 32 bytes, it's possible to overflow past the end of the last element in the mixer_vols array. Further exploitation can result in an arbitrary kernel write (via subsequent calls to load_mixer_volumes()) leading to privilege escalation, or arbitrary kernel reads via get_mixer_levels(). In addition, the strcmp() may leak bytes beyond the mixer_vols array.

commit 3f343f8512c7882a3637d9aea4ec6b3801cbcdc5 upstream.

2011-01-07ALSA: hda: Use model=lg quirk for LG P1 Express to enable playback and captureDaniel T Chen
commit 77c4d5cdb81d25a45fbdfb84dd3348121219a072 upstream. BugLink: https://launchpad.net/bugs/595482 The original reporter states that audible playback from the internal speaker is inaudible despite the hardware being properly detected. To work around this symptom, he uses the model=lg quirk to properly enable both playback, capture, and jack sense. Another user corroborates this workaround on separate hardware. Add this PCI SSID to the quirk table to enable it for further LG P1 Expresses.
