[Spice-devel] [spice-server v1 1/3] clang: Don't compute absolute value of unsigneds

[Victor Toso]

From: Victor Toso <me at victortoso.com>

Clang's warning on absolute-value.

> red-record-qxl.c:297:39: error: taking the absolute value of unsigned
> type 'uint32_t' (aka 'unsigned int') has no effect
>     bitmap_size = qxl->bitmap.y * abs(qxl->bitmap.stride);
>                                   ^
> red-record-qxl.c:297:39: note: remove the call to 'abs' since unsigned
> values cannot be negative
>     bitmap_size = qxl->bitmap.y * abs(qxl->bitmap.stride);
>                                   ^~~
