From 2712a7d362904d0c4283ae91fac8cea6ecd6f9c2 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 22 May 2025 12:57:26 +0200 Subject: [PATCH] spi: gpio: fix const issue in spi_to_spi_gpio() While the struct spi_device * passed into spi_to_spi_gpio() is a const one, the struct spi_bitbang * that is retrieved from the controller field in the spi_device is NOT a const pointer, as it is coming from the spi_controller_get_devdata() call, and then passed to container_of() which would strip off the const attribute for no good reason (i.e. if a const pointer is passed to container_of() it still is const coming out). Fix this all up by properly declaring the struct spi_bitbang * as not const.
