BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit fb0b3225 ] Shifting a u8 by 24 will cause the value to be promoted to an integer. If the top bit of the u8 is set then the following conversion to an unsigned long will sign extend the value causing the upper 32 bits to be set in the result. Fix this by casting the u8 value to an unsigned long before the shift.
