David Ward f3162bafa8 Replace variable self-assignments to avoid Clang warnings 
These were intended to suppress GCC warnings about unused variables.
However, this leads to different warnings from Clang instead.

Use another approach that suppresses warnings from both compilers.

David Ward 4cf3b09e49 rts8822, rts8891: Replace abs() with fabs() where needed 
abs() has an integer parameter and returns an integer value. Floating-
point values should be passed to fabs() instead.

In particular, this affected calculations for gain and offset, where a
value with floating-point precision is clearly expected.

Olaf Meeuwissen 328a5d654b hp3900: Fix [-Wtautological-compare] compiler warning 
Although the fix changes the backend's logic, it probably matches what
was the original code's intent.
