[libcamera-devel] [PATCH] libcamera: ipu3: Fix compilation issues with gcc5

[Jacopo Mondi]

GCC5 does not provide prototypes for the math library functions defined
in the math.h header for the std:: namespace.

Include the C++ <cmath> header in place of <math.h> as it defines
overloads for the std::abs and std::fmod function.

This goes intentionally against the libcamera coding guidelines, and
is reported as warning by checkpatch.py.

Fixes: 968ab9bad0ed ("libcamera: ipu3: imgu: Calculate ImgU pipe configuration")
