Hi "Yannick,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linus/master]
[also build test WARNING on v5.1-rc2 next-20190329]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Yannick-Fertr/drm-bridge-sii902x-initialize-CEC-device/20190330-102132
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'


sparse warnings: (new ones prefixed by >>)

>> drivers/gpu/drm/bridge/sii902x.c:485:5: sparse: symbol 'sii902x_cec_init' was not declared. Should it be static?

Please review and possibly fold the followup patch.
