Message

Microchip NTB devices support up to 512 LUTs shared across all NT
partitions. This short patch series increases MAX_MWS to 256 and also
address issues when the number of mw is equal to 0 or MAX_MWS

Maciej Grochowski (3):
  ntb: ntb_hw_switchtec: Fix shift-out-of-bounds for 0 mw lut
  ntb: ntb_hw_switchtec: Fix array-index-out-of-bounds access
  ntb: ntb_hw_switchtec: Increase MAX_MWS limit to 256
