re: [PATCH] spi: hisi-kunpeng: Fixed the wrong debugfs node name in hisi_spi debugfs initialization

[liudingyuan]

> In hisi_spi_debugfs_init, spi controller pointer is calculated by container_of macro, and the member is hs->dev. But the host pointer cannot be calculated offset directly by this, because hs->dev points to the device in platform device(pdev->dev), and it is > the host->dev.parent points to the pdev->dev, which is set in __spi_alloc_controller.

>In this patch, this issues is fixed by getting the spi_controller data from pdev->dev->driver_data directly, driver_data points to the spi controller data in the probe stage.

Gentle ping on this patch.
