commit 5ff8aca906f3a7a7db79fad92f2a4401107ef50d upstream.
The call to pinctrl_count_index_with_args checks for a -EINVAL return however this function calls pinctrl_get_list_and_count and this can return -ENOENT. Rather than check for a specific error, fix this by checking for any error return to catch the -ENOENT case.
