Hi!

commit 64bbacc5f08c01954890981c63de744df1f29a30 upstream.
skl_print_pins() loops over all given pins but it overwrites the text at the very same position while increasing the returned length. Fix this to show the all pin contents properly.

This may be an improvement, but I believe this should use "scnprintf()" as snprintf can return values bigger than size passed in.
