Thomas Gleixner a0af3d1104 PCI/MSI: Prevent UAF in error path ... When the core MSI allocation fails, then the PCI/MSI code uses an already freed MSI descriptor to unmask the MSI mask register in order to bring it back into reset state. Remove MSI_FLAG_FREE_MSI_DESCS from the PCI/MSI irqdomain flags and let the PCI/MSI code free the MSI descriptors after usage.
