This patches addresses following problem: rtc_allocate_device devm_device_add_group <-- kernel oops / null pointer, because sysfs entry does not yet exist rtc_register_device rc = devm_device_add_group if (rc) return rc; <-- forbidden to return error code after device register This patch adds rtc_add_group(s) functions. The functions store the sum of attribute groups as device resource. Signed-off-by: Denis Osterland <Denis.Osterland@diehl.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
