From: Ian Stokes <ian.sto...@intel.com>
Fix a static analysis warning where if the 16-bit value in mask has the high-bit
set, it will be sign extended by the shift left (which converts it to a signed
integer). Avoid this by casting to a u32 to make sure the conversion happens
before the shift and that it stays unsigned.
