I didn't tag all the places that need it, but I'd be tempted to go with sizeof(dst) rather than a #define that may or may not be right and requires extra brain power to go check for each case.
Even w/o it, the change is an improvement.

| 689 | this actually did NUL terminate. It wasn't safe though. I'd make a note of the migration from the unsafe / hard-to-user interfaces to the strl interfaces in the commit. | |
| 690 | the traditional thing here is 'sizeof(ccb->cgdl.periph_name)' instead of some random #define that may be right or wrong. We know the CCBs preallocate so we don't have to worry about the pointer issue. | |
| 1760 | Same sizeof comment for this argument. | |

Looks good, assuming you put sizeof() in there.

| 690 | I agree with the sizeof() thing. That would be the better way to do it. | |
