4eb42b81c552f9cd4d13bfbf26bbfe95c9cc7072 pci: designware: Update MSI mapping unconditionally
Expression to calculate update_msi_mapping in code handling writes to
DESIGNWARE_PCIE_MSI_INTR0_ENABLE is missing an ! operator and should
be:
!!root->msi.intr[0].enable ^ !!val;
so that MSI mapping is updated when enabled transitions from either
"none" -> "any" or "any" -> "none". Since that register shouldn't be
written to very often, change the code to update MSI mapping
unconditionally instead of trying to fix the update_msi_mapping logic.
