Title
PCI: cadence: Check for the existence of cdns_pcie::ops before using it
Summary
In the Linux kernel, the following vulnerability has been resolved: PCI: cadence: Check for the existence of cdns_pcie::ops before using it cdns_pcie::ops might not be populated by all the Cadence glue drivers. This is going to be true for the upcoming Sophgo platform which doesn't set the ops. Hence, add a check to prevent NULL pointer dereference. [mani: reworded subject and description]

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
