Do you mind explaining the logic of this pin fixup as driver also change
max channels from 2 to 4 ?

The parser put one headphone in the line_outs before your patch but type is
still line

autoconfig for ALC269VB: line_outs=1 (0x21/0x0/0x0/0x0/0x0) type:line
   speaker_outs=1 (0x14/0x0/0x0/0x0/0x0)
   hp_outs=1 (0x1a/0x0/0x0/0x0/0x0)
   mono: mono_out=0x0
   inputs:
     Internal Mic=0x12
     Mic=0x18

the headphone and dock headphone was put in the hp_outsafter your patch

autoconfig for ALC269VB: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker
   speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
   hp_outs=2 (0x1a/0x21/0x0/0x0/0x0)
   mono: mono_out=0x0
   inputs:
     Internal Mic=0x12
     Mic=0x18


Do the driver need to distinguish between

notebook with headphone and Dock headphone
notebook with dual headphone jacks
