dwc2_hs_pmap_unschedule(9)

💅 dwc2_hs_pmap_unschedule(9) 💅

okay so bestie, welcome to the Kernel API Manual page for dwc2_hs_pmap_unschedule(9). It's the function that undoes the work done by dwc2_hs_pmap_schedule() — literally the cleanup era, no cap. ✨

🌸 NAME 🌸

dwc2_hs_pmap_unschedule — Undo work done by dwc2_hs_pmap_schedule()

✨ SYNOPSIS ✨

The signature is exactly this, bestie:

       void dwc2_hs_pmap_unschedule (struct dwc2_hsotg *hsotg , struct dwc2_qh
       *qh , int index );

It returns void, so there's no return value to catch — it's giving "do the cleanup and go" energy. 💅

🎀 ARGUMENTS 🎀

• hsotg — The HCD state structure for the DWC OTG controller. That's the controller-state bestie. 🫶
• qh — QH for the periodic transfer. The exact QH this page is talking about. 🌸
• index — Transfer index. Yes, the index of the transfer. 🎀
