| 2 | Subject: ALSA: hda - Fix caching of SPDIF status bits | |
| 3 | Patch-mainline: | |
| 4 | References: | |
| 5 | ||
| 6 | SPDIF status bits controls are written via snd_hda_codec_write() | |
| 7 | without caching. This causes a regression at resume that the bits | |
| 8 | are lost. | |
| 9 | ||
| 10 | Simply replacing it with the cached version fixes the problem. | |
