From 8fcb830a00f0980ffe38d223cdd9a4d2d24da476 Mon Sep 17 00:00:00 2001 From: Volker Haspel Date: Tue, 12 Mar 2019 11:12:03 +0100 Subject: [PATCH] spi: spi-fsl-qspi: use devm_spi_register_controller The driver does not clearly unregister the spi controller. Therefore calling an unbind and bind again will end up in a Kernel crash. The function devm_spi_register_controller will automatically be unregister the SPI device.
