Merge pull request #1 from ARMmbed/master …

Can you rebase this instead please? (to remove this merge commit)

[0xc0170]

Code looks good, just needs a rebase

[fredlee12001]

Rebase to master instead of create PR.

[0xc0170]

I noticed the style is different (the rest of file has it fine)

int gpio_is_connected(const gpio_t *obj)
{
}

{ on the new line.

Thanks for the rebase, this shall be ready for CI once fixed

[fredlee12001]

Changed and Keep same coding style with others.
