Hi Stefan,

I love your patch! Perhaps something to improve:

[auto build test WARNING on tegra-drm/drm/tegra/for-next]
[also build test WARNING on v4.18-rc1 next-20180619]
[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/Stefan-Mavrodiev/drm-panel-Add-support-for-Olimex-LCD-OLinuXino-panel/20180619-180429
base:   git://anongit.freedesktop.org/tegra/linux.git drm/tegra/for-next
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> drivers/gpu/drm/panel/panel-olimex-lcd-olinuxino.c:215:24: sparse: symbol 'lcd_olinuxino_funcs' was not declared. Should it be static?

Please review and possibly fold the followup patch.
