> * Inclusion of upstream f6028eeeb5e4: "coresight: core: Disable helpers for devices that fail to enable" added two calls to coresight_disable_helpers() with an additional path parameter, which is not available in the current function call, which only accepts coresight_disable_helpers(struct coresight_device *csdev). This causes the kernel to fail to build when coresight is enabled.
