Hi Jan,

CVE-2020-25669[0] is a CVE for SUNKBD (sun4/sun5 keyboard), which is
enabled in siemens_i386-rt kernel.

```
$ git grep SUNKBD
4.19.y-cip-rt/x86/siemens_i386-rt.config:# CONFIG_KEYBOARD_SUNKBD is not set
4.19.y-cip/x86/plathome_obsvx2.config:# CONFIG_KEYBOARD_SUNKBD is not set
4.19.y-cip/x86/siemens_iot2000.config:# CONFIG_KEYBOARD_SUNKBD is not set
4.4.y-cip-rt/x86/siemens_i386-rt.config:CONFIG_KEYBOARD_SUNKBD=m
4.4.y-cip/arm/siemens_am57xx-pxm3.config:# CONFIG_KEYBOARD_SUNKBD is not set
4.4.y-cip/arm/siemens_imx6_defconfig:# CONFIG_KEYBOARD_SUNKBD is not set
4.4.y-cip/x86/plathome_obsvx1.config:# CONFIG_KEYBOARD_SUNKBD is not set
4.4.y-cip/x86/siemens_iot2000.config:# CONFIG_KEYBOARD_SUNKBD is not set
```

Is this driver used? If you're not using it, I'd consider removing it from the kernel's
config to support this CVE. Could you give me your opinion on this?


Best regards,
Nobuhiro
