This patch series addresses a long-standing design issue in the PCI/MSI subsystem where the implicit, automatic management of IRQ vectors by the devres framework conflicts with explicit driver cleanup, creating ambiguity and potential resource management bugs. ==== The Problem: Implicit vs. Explicit Management ==== Historically, `pcim_enable_device()` not only manages standard PCI resources (BARs) via devres but also implicitly triggers automatic IRQ vector management by setting a flag that registers `pcim_msi_release()` as a cleanup action.

Sorry, this is a mistake. This patch is not applied. - Mani -- மணிவண்ணன் சதாசிவம்
