This patch fix this bug by correcting 'DP_OUT_MUX' to 'DPTX_OUT_MUX'. [ Test Plan ] Reproduce: 1. Install Ubuntu 22.04 (jammy) on a MediaTek G700 device 2. Run `alsactl init` on MediaTek G700 device 3. alsactl print error message "unable to execute cset 'name='DP_OUT_MUX' Disconnect'" and audio devices do not work. Verify: By applying this patch, alsactl does not print this error message and audio devices work. [Where problems could occur] This patch fix the typo in ucm files, and it affects the device init process on Mediatek Genio boards. [ Other Info ] There is a typo in 'd/p/0001-Add-initial-support-for-MediaTek-Genio-boards.patch'. The name of the flag that controls the audio output of the DP port is not 'DP_OUT_MUX'. It is 'DPTX_OUT_MUX'.
