[PATCH 2/2] drm/exynos: 'win' is always unsigned

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The index for the hardware layer is always >=0. Previous
code that also used -1 as special index is now gone.

Also apply this to 'ch_enabled' (decon/fimd), since the
variable is on the same line (and is again always unsigned).
