I didn't check this one, because it's not the most useful one. But it also doesn't really hurt, so I'm fine with it either way.
Note that the error code returned by the dc_serial_close() function is mainly for informative purposes anyway. The caller can't really do much with it other then reporting it.
I'm fine either way - we can always mark this as intentional in Coverity (btw, you haven't asked for access to the scan reports - can you see the reports without me giving you access after all?)
I simply added these checks because in general libdivecomputer is extremely consistent and conservative with error checking, so this did seem like an unintentional omission to me.
