However, show_dynamic_id() has the type of the ->show() callback in 'struct device_attribute', which causes a CFI violation when opening the 'id' sysfs node under drm/card0/metrics. This happens to work because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast happens to allow the ->show() callback to still work. Change the type of show_dynamic_id() to match the ->show() callback in 'struct kobj_attributes' and update the type of sysfs_metric_id to match, which resolves the CFI violation.

First, single link DSI needs to use the configured port instead of relying on the VBT sequence block port. Remove the hard-coded port C check here and make it generic. For reference, see commit f915084edc5a ("drm/i915: Changes related to the sequence port no for") for the original VLV specific fix. Second, the sequence block port number is either 0 or 1, where 1 indicates the 2nd link. Remove the hard-coded port C here for 2nd link. (This could be a "find second set bit" on DSI ports, but just check the two possible options.) Third, sanity check the result with a warning to avoid a NULL pointer dereference.
