There is an undefined bitwise shift behavior, when the right operand is
greater than or equal to then width of the promoted left operand.
(eg: (u32)data << 32). Commit bc8263083af6("fix an undefined bitwise shift
behavior") only fixed one problem, there are many similar problems in
drivers/net/wireless/realtek/.
This patchset adds a new function calculate_bit_shift() to fix the
remaining undefined bitwise shift behavior problems.(Compile tested only)
