From a63abe389d56f6f7b1541c2084b453c9dfdb89dc Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 4 Dec 2015 20:20:09 -0200 Subject: [PATCH] [media] exynos4-is: make VIDEO_SAMSUNG_EXYNOS4_IS tristate With CONFIG_V4L2=m and VIDEO_SAMSUNG_EXYNOS4_IS=y, we can select the individual drivers as built-in code when that should not be possible: drivers/built-in.o: In function `s5pcsis_set_fmt': policy.c:(.text+0x13afdc): undefined reference to `v4l_bound_align_image' drivers/built-in.o: In function `s5pcsis_probe': policy.c:(.text+0x13b440): undefined reference to `v4l2_of_parse_endpoint' policy.c:(.text+0x13b72c): undefined reference to `v4l2_subdev_init' Changing VIDEO_SAMSUNG_EXYNOS4_IS to tristate means that the dependency from CONFIG_V4L2 propates to the individual Kconfig symbols and they can only be built as loadable modules if V4L2 or any other of the dependencies itself is a module.
