π pch_udc_clear_ep_control(9) β β¨ Kernel API Manual β¨
okay so bestie, welcome to the Kernel API Manual entry for pch_udc_clear_ep_control(9) β yes that's the whole title, she's long, she's iconic, she ate π this is the page where we clear the endpoint control register and feel cute about it.
πΈ NAME πΈ
pch_udc_clear_ep_control β literally just Clear the endpoint control register. that's the vibe. that's the whole job. no cap π
π¦ SYNOPSIS π¦
void pch_udc_clear_ep_control (struct pch_udc_ep *ep );
look at her. void return, one argument, zero drama. main character energy fr π«Ά
π ARGUMENTS π
one (1) single argument, and she matters:
epβ a Reference to structure of typepch_udc_ep_regs. and then βRetern(help, that's genuinely how this page spells it, i'm not fixing her, we respect the typo's journey π) β The endpoint control register value.
π§ note bestie: that's what the page says, word for word-ish, so that's what you get. we don't invent lore here, we just report it with love.
β SEE ALSO β
okay this part is a LOT β like a full group chat of functions all @'ing each other. but every single one is here, nobody got left on read π₯Ίπ«Ά

like i said. the whole group chat. π
and that's the page bestie!! ππ« this one came from the source path ./drivers/usb/gadget/udc, dated October 2026, and it's living under the pch_udc_clear_ep_control(9) name in the Kernel API Manual β go clear that endpoint control register and slay, ily, bye πππ¦
