HID: hid-roccat-koneplus: potential NULL dereference
kmalloc() may fail, if so return -ENOMEM. Also koneplus_init_koneplus_device_struct() should check return code of koneplus_get_startup_profile() and propagate its return code. Signed-off-by: Vasiliy Kulikov <segoon@openwall.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
