From: Wei Chen wei.chen@arm.com
In current vexpress_config_probe code, it sets the uclass private data directly. This will cause one compilation error: drivers/misc/vexpress_config.c:114:27: error: lvalue required as left operand of assignment 114 | dev_get_uclass_priv(dev) = priv; | ^
In this patch we set the uclass private data through struct member .priv_auto, and this compilation error disappears.
