| |
This is patch for Conexant codec of Intel HDA driver, adding new quirk for Lenovo Thinkpad T520 and W520. Conexant autodetection works fine for T520 (similar subsystem ID is used also in W520 model) and detects more mixer features compared to generic (fallback) Lenovo quirk with hardcoded options in Conexant codec.
Patch was activelly tested with Linux 3.0.4, 3.0.6 and 3.0.7 without any problems.
