Indirect call in vesafb driver

[Alexander Pateenok <pateenoc@xxxxxxxxx>]

Hi,

There're several indirect calls in inline assembly in vesafb driver
(drivers/video/fbdev/vesafb.c), and these calls cannot be automatically
changed to retpolines. It's in vesafb_pan_display():

   73        __asm__ __volatile__(
   74                "call *(%%edi)"

and in vesa_setpalette():

  113        __asm__ __volatile__(
  114         "call *(%%esi)"

Is there need to use CALL_NOSPEC ?

Thanks, Alex
