[PATCH] drm/amd/display: Use kcalloc() instead of kzalloc()

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

 



We are trying to get rid of all multiplications from allocation
functions to prevent integer overflows. Here the multiplication is
obviously safe, but using kcalloc() is more appropriate and improves
readability. This patch has no effect on runtime behavior.
