Patch 6 opts dps310.o into the analysis, so they are checked and not just
documentation. Clean under clang 23.1.0, and it does run: dropping the
lock around dps310_fill_scan() fails the build. Patch is last and touches
only the Makefile, so drop it if IIO would rather not opt in yet.

Plain lock and unlock in the trigger handler and in the FIFO work. Kept
guard() in the three places where the lock covers a whole function.
