[PATCH 0/3] mailbox: zynqmp-ipi: Improve resource cleanup on driver unbind

From: Harini T
Date: Fri Aug 22 2025 - 00:58:04 EST


1. Remove redundant mbox_controller_unregister() call, as
device_unregister() already handles controller cleanup.
2. Fix the mailbox cleanup loop to prevent out-of-bounds array access by
starting at num_mboxes-1.
3. Fix SGI resource cleanup by using an explicit irq_type field for
reliable SGI detection, replacing the unreliable IRQ number check.
