[PATCH HID 07/13] HID: bpf: convert in-tree fixes into struct_ops

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Very mechanical:
- Change HID_BPF_DEVICE_EVENT and HID_BPF_RDESC_FIXUP #defines
- add a matching SEC(".struct_ops.link")
- in ArtistPro16Gen2 make the 2 functions static and have a new one
  calling them
