- max_size = (be->max < max_size) ? be->max : max_size;
min() / max() ?
The use of min() and min3() seems to generate tons of sparse warnings (see below), so I'll leave the code with an explicit test and a comment stating why.
sparse helped us find quite a few issues with endianess, const, iomem qualifiers, I'd like to keep it quiet on non-issues.
