Similarly for Kukjin, he's listed as the main Samsung maintainer already, 
but AFAIK in this case the script can't infer this based on directory 
structure. Let's see how it's done for other Samsung drivers:

DRM DRIVERS FOR EXYNOS
M:      Inki Dae <inki.dae@...sung.com>
M:      Joonyoung Shim <jy0922.shim@...sung.com>
M:      Seung-Woo Kim <sw0312.kim@...sung.com>
M:      Kyungmin Park <kyungmin.park@...sung.com>
L:      dri-devel@...ts.freedesktop.org
T:      git git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-
exynos.git
S:      Supported
F:      drivers/gpu/drm/exynos
F:      include/drm/exynos*
F:      include/uapi/drm/exynos*

EXYNOS DP DRIVER
M:      Jingoo Han <jg1.han@...sung.com>
L:      linux-fbdev@...r.kernel.org
S:      Maintained
F:      drivers/video/exynos/exynos_dp*
F:      include/video/exynos_dp*

EXYNOS MIPI DISPLAY DRIVERS
M:      Inki Dae <inki.dae@...sung.com>
M:      Donghwa Lee <dh09.lee@...sung.com>
M:      Kyungmin Park <kyungmin.park@...sung.com>
L:      linux-fbdev@...r.kernel.org
S:      Maintained
F:      drivers/video/exynos/exynos_mipi*
F:      include/video/exynos_mipi*

ARM/SAMSUNG S5P SERIES 2D GRAPHICS ACCELERATION (G2D) SUPPORT
M:      Kyungmin Park <kyungmin.park@...sung.com>
M:      Kamil Debski <k.debski@...sung.com>
L:      linux-arm-kernel@...ts.infradead.org
L:      linux-media@...r.kernel.org
S:      Maintained
F:      drivers/media/platform/s5p-g2d/

and so on.

So I think, based on this precedent, we can do the same for pinctrl. Let's 
wait to see Thomas' view on this.

Best regards,
Tomasz
