Hi,
here is a largish patch set mostly for cleanup / a slight refactoring of the coding styles with assignment in if condition, typically such as: if ((err = xxx()) < 0) return err;
This was a popular style in the old ages, but nowadays it's seen rather fairly harmful as it makes harder to read and easily hides bugs. Since we've hit quite a few issues (although most of them are trivial), I decided to fix those lines.
While conversions, I spotted a couple of real bugs. They are old driver codes and only in certain error paths, so most likely no one ever hits it.
