Bisect sequence went 56+ 84+ 98+ 105- 102- 100+ 101+. Looks like 102's to blame: driver-core-check-return-code-of-sysfs_create_link.patch From: Cornelia Huck <cornelia.huck@...ibm.com> Check for return value of sysfs_create_link() in device_add() and device_rename(). Add helper functions device_add_class_symlinks() and device_remove_class_symlinks() to make the code easier to read. -- Mathematics is the supreme nostalgia of our time. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
