ldn

• Updated L_2c670, prev ver @ L_2c670.
  • This is the func which initializes the service objects.

  • InitializePortImpl for ldn:m had max_sessions changed from 5 to 6.
• Updated L_2cdec, prev ver @ L_2cdcc. Updated L_2d0bc, prev ver @ L_2d074.
  • These now support using two additional entry slots.
• Updated L_2d520, prev ver @ L_2d4ac.
  • At the end two additional decref vfunc calls are done with two objects, if needed.

am

Besides the new IPC cmd / IPC changes from updated SDK:

• Updated L_47300, prev ver @ L_47300.
  • State init was updated.
• Updated L_5bd90, prev ver @ L_5bd60.
• Updated L_5d2a8, prev ver @ L_5d258.
• Updated L_645f0, prev ver @ L_64510.
  • L_6fdf0 is now called with an additional param, w2=0x1.
• Updated L_6fdf0, prev ver @ L_6fd00.
  • The new inw2 param is now passed to L_138040 w2 (additional input param for hid:sys RegisterAppletResourceUserId).
  • As of 20.2.0 hid:sys (on NX at least) doesn't currently handle this new param.
• Updated L_704d4, prev ver @ L_703d4.
  • At the end before writing the u32 0x0 to output, this now runs the same check as immediately before the prior func call (Abort when a state field is set).
• Updated L_70600, prev ver @ L_70500. Updated L_70bc0, prev ver @ L_70aa4.
  • The output from L_704d4 is now copied to inx0+0x30.

ssl

• The only change was updating L_11ab20, prev ver @ L_11ab20.
  • During the loop it would originally return 1 when the func call is successful. Now when that's successful, L_4cb20 is now called, with 1 being returned when ret==1.
  • Otherwise, it continues the loop.

grc

The only changes are IPC related (on NX the only changed func was the IPC handler for the updated interface).
