[PATCH] video: nexell: unsigned parameter cannot be negative

[Andrew Goodbody]

The parameter 'alpha' is declared as an unsigned type so cannot be
negative. The code to test it as being less than zero will always fail
and so is redundant and should be removed.

This issue was found by Smatch.

There is no call to this function currently in the tree so maybe it
should just be removed entirely?
