67ba7a82d9 drm/panel: novatek-nt36672e: use wrapped MIPI DCS functions 
Remove conditional code and always use mipi_dsi_dcs_*multi() wrappers to
simplify driver's init/exit code. This also includes passing context to
the init_sequence() function instead of passing the DSI device.

d6fcbec281 drm/panel: novatek-nt36672e: Switch to mipi_dsi_dcs_write_seq_multi() 
This is a mechanical conversion of the novatek-nt36672e driver to use
the new mipi_dsi_dcs_write_seq_multi(). The new function is easier for
clients to understand and using it also causes smaller code to be
generated. Specifically:

  ...after/panel-novatek-nt36672e.ko \
  ...ctx/panel-novatek-nt36672e.ko

302aeb9467 drm/panel: novatek-nt36672e: stop setting register load before disable 
It is pointless to set register load before disabling the register. This
vote is going to be dropped as soon as the register is disabled. Drop
these register_set_load calls.

941c0bdbc1 drm/panel: novatek-nt36682e: don't unregister DSI device 
The DSI device for the panel was registered by the DSI host, so it is an
error to unregister it from the panel driver. Drop the call to
mipi_dsi_device_unregister().
