splitting parameters rather than declaration

I'm trying to get clang-format to do my bidding, and stumbling on one point. I want my C function declaration to be formatted as:

sensor_t *sensor_enable_alarm(sensor_t *sensor, 
                              float lo_thresh, 
                              float hi_thresh);

but with my current settings, clang-format wants to format it as:

sensor_t *
sensor_enable_alarm(sensor_t *sensor, float lo_thresh, float hi_thresh);

I've initialized my .clang-format from llvm via:

clang-format -style=llvm -dump-config > .clang-format

and modified just the BinPackParameters to be false:

BinPackParameters: false

What additional tweaks to .clang-format do I need?

This can be done by setting PenaltyReturnTypeOnItsOwnLine to a larger value. The default value for LLVM style is 60. Try 200, which is the default for Google, Mozilla, and Chromium styles.

For example, clang-format -style='{BasedOnStyle: LLVM, BinPackParameters: false, PenaltyReturnTypeOnItsOwnLine: 200}' yourfile.cpp gives this output:

sensor_t *sensor_enable_alarm(sensor_t *sensor,
                              float lo_thresh,
                              float hi_thresh);

As always, see the documentation for more information. However, unfortunately, there really isn't much there to explain the "Penalty" values.
