6.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Zhang Lixu <lixu.zhang@xxxxxxxxx> [ Upstream commit 92826905ae340b7f2b25759a06c8c60bfc476b9f ] The variable dev->devc in ish_dev_init was utilized by dev_err before it was properly assigned. To rectify this, the assignment of dev->devc has been moved to immediately follow memory allocation. Without this change "(NULL device *)" is printed for device information.
