_snd_hda_set_pin_ctl(9)

💖 NAME 💖

_snd_hda_set_pin_ctl — helper to set pin ctl value. Welcome to the _snd_hda_set_pin_ctl(9) page from the Kernel API Manual, bestie! 💅

✨ SYNOPSIS ✨

int _snd_hda_set_pin_ctl (struct hda_codec *codec , hda_nid_t pin ,
       unsigned int val , bool cached );

🎀 ARGUMENTS 🎀

• codec — the HDA codec. main character energy, honestly.
• pin — the referred pin NID.
• val — the pin control value to set.
• cached — access over codec pinctl cache or direct write. iykyk.

🌸 DESCRIPTION 🌸

Okay so this function is a helper to set a pin ctl value more safely. It’s giving careful-bestie behavior, fr fr.

It corrects the pin ctl value via snd_hda_correct_pin_ctl, stores the value in pin target array via snd_hda_codec_set_pin_target, then actually writes the value via either snd_hda_codec_write_cache or snd_hda_codec_write depending on cached flag. No cap. 💖
