Subject[PATCH] extcon: arizona: Ensure variables are set for headphone detection
Date
The detecting flag really refers to the microphone detection stage and
as such should be cleared before arizona_identify_headphones is called.
Also the mic flag should be set before identify headphones is called as
well.

Note this was generated on top of the other patch chain I sent today.

Thanks,
