Although unbinding a driver requires root privileges but it still might
be used theoretically in certain attacks (by triggering NULL pointer

Samsung clock drivers are essential for system operation so their
removal is not expected. More over, the Exynos3250 ISP clock driver does
not implement remove() driver callback and it is not buildable as
modules.

Suppress the unbind interface for Exynos3250 ISP and S3C2410 DCLK clock
drivers.
