pmcraid_release_chrdev(9)

💅 pmcraid_release_chrdev(9) — the Kernel API Manual moment 🎀

okay so bestie, we're in the pmcraid corner of the kernel today, and this is the page for pmcraid_release_chrdev, a <pink>Kernel API Manual</pink> entry — yes it's a section 9 page, yes it's driver-internals hours, stay with me 🦋

---

✨ NAME ✨

pmcraid_release_chrdev — the function that unregisters the per-adapter management interface. that's it, that's the whole vibe. it's the "we're done here, pack up the char device" girlie 💅

---

🌸 SYNOPSIS 🌸

void pmcraid_release_chrdev (struct pmcraid_instance *pinstance );

literally one line, no drama, no return type shenanigans — it's a void, she gives nothing back and she's fine with that ✨

---

🎀 ARGUMENTS 🎀

• pinstance — pointer to the adapter instance structure. so like, you hand her the adapter's own little instance struct and she knows exactly which adapter's management interface to unregister. iykyk 🫶

---

💖 DESCRIPTION 💖

okay so the description here is genuinely three words long and i respect the confidence: Return value none. that's it. nothing gets returned, nothing gets reported back, she does her job and dips 😭 no cap.

like — she unregisters the per-adapter management interface (that's the NAME section tea from earlier, not me inventing lore), and that's the entire documented story. periodt 💀

heads up bestie: the synopsis is void, and DESCRIPTION literally only says "Return value none" — so don't go looking for an error code, there isn't one documented here 💀

and that's the page!! this cutie lives in <mint>./drivers/scsi</mint> and the manual page itself is dated October 2026 🌈 mwah, go unregister something responsibly, ily, bye 🍓💜
