iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init()
commit efa17e90e1711bdb084e3954fa44afb6647331c0 upstream.
dev_set_name() allocates memory for name, it need be freed
when device_add() fails, call put_device() to give up the
reference that hold in device_initialize(), so that it can
be freed in kobject_cleanup() when the refcount hit to 0.

iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init()
commit efa17e90e1711bdb084e3954fa44afb6647331c0 upstream.
dev_set_name() allocates memory for name, it need be freed
when device_add() fails, call put_device() to give up the
reference that hold in device_initialize(), so that it can
be freed in kobject_cleanup() when the refcount hit to 0.
