Using the return value to report errors is error prone: - xics_alloc() returns -1 on error but spapr_vio_busdev_realize() errors on 0 - xics_alloc_block() returns the unclear value of ics->offset - 1 on error but both rtas_ibm_change_msi() and spapr_phb_realize() error on 0 This patch adds an errp argument to xics_alloc() and xics_alloc_block() to report errors. The return value of these functions is a valid IRQ number if errp is NULL. It is undefined otherwise. The corresponding error traces get promotted to error messages. Note that the "can't allocate IRQ" error message in spapr_vio_busdev_realize() also moves to xics_alloc(). Similar error message consolidation isn't really applicable to xics_alloc_block() because callers have extra context (device config address, MSI or MSIX). This fixes the issues mentioned above.
