[M120 Migration] Fix build warning

The following patch fixes a compilation warning [1] that
occurs during tv build.

[1] "warning: comparison of integers of different
signs: 'int' and 'unsigned int'"

The upper limit of unsigned int and int are different, so in
extreme cases where value of a variable falls in between the
upper limit of int and unsigned int, leads to an infinite loop.
