[PATCH v2] bus: mhi: host: pci_generic: Sort mhi_pci_id_table based on the PID
Posted by Manivannan Sadhasivam 4 years ago 
Sorting this way helps in identifying the products of vendors. There is no
sorting required for VID and the new VID should be added as the last entry.

Let's also add a note clarifying this.

Changes in v2:

* Fixup the 0x0306 entry by moving it after subid

I will wait for this change to be merged, then rebase the FN980 one.
