[U-Boot] [PATCH V3 1/3] dm: gpio: request list: return the count if requests max_count reached

[Przemyslaw Marczak]

The function gpio_request_list_by_name_nodev() returned -ENOSPC error,
when the loop count was greater than requested count. This was wrong,
because function should return the requested gpio count, when meets
the call request without errors. Now, the loop ends on requested
max_count.
