[PATCH] pinctrl: samsung: Use snprintf() to construct pin bank names

[Mariia Nikitash <nikitash.mariiaw@gmail.com>]

From: Bill Wendling <morbo@google.com>

samsung_banks_node_get() constructs each pin bank node name by copying
bank->name with strscpy() and appending the suffix with strlcat().

In preparation for removing the deprecated strlcat() API[1], format the
node name in a single snprintf() call, which preserves the existing
truncation check against sizeof(node_name).
