[ Upstream commit cd7fdc45bc69a62b4e22c6e875f1f1aea566256d ]
Add suffix ULL to constant 256 in order to give the compiler complete information about the proper arithmetic to use.
Notice that such constant is used in a context that expects an expression of type u64 (64 bits, unsigned) and the following expression is currently being evaluated using 32-bit arithmetic:
256 * fs * 2 * mclk_src_scaling[i].param
