From 23e3404de1aecc62c14ac96d4b63403c3e0f52d5 Mon Sep 17 00:00:00 2001 From: Kunihiko Hayashi Date: Wed, 22 Dec 2021 13:48:12 +0900 Subject: spi: uniphier: Fix a bug that doesn't point to private data correctly In uniphier_spi_remove(), there is a wrong code to get private data from the platform device, so the driver can't be removed properly. The driver should get spi_master from the platform device and retrieve the private data from it.
