In ODM_TxPwrTrackSetPwr_8723B(), Final_OFDM_Swing_Index and
Final_CCK_Swing_Index are declared as u8. Using u8 for variables involved
in arithmetic calculations and lower-bound comparisons (<= 0) is unusual
and triggers static analysis warnings.

Convert both variables from u8 to int to clean up the variable types,
aligning with the TODO item to "convert any remaining unusual variable
types".

What warnings?

u8 is NOT an unusual variable type at all.

Indeed, but doing arithmetic on u6 and u16 is likely to be less efficient
because the compiler has to mask the results (on pretty much all architectures
except x86 and m68k).
But that isn't the reason given.
