Did you update your master to the upstream master? There are conflicts, although you added new commits just 3 hours ago. Will look at the conflicts

[bcostm]

No I didn't do it before these commits. Can you tell me which conflicts you see ?

[0xc0170]

Thanks for resolving the conflicts. It's a good practice to rebase your branch to the latest master's HEAD, to resolve all conflicts before issuing a new pull request. Same when starting adding a new feature, to start from the latest changes.

I have just noticed, you removed from gpio_objects header file the function:

static inline int gpio_is_connected(const gpio_t *obj) {
    return obj->pin != (PinName)NC;
}

I'll send the new PR to fix this.

I didn't see it. It is a new function that has been added recently. Thanks for the update.

I do a diff when I am about to commit changes, to see if all files contain changes I have done, not introducing any new. Diff tool might help for this type of paste-replace, to only apply new differences and keep the old ones in the place.
