From b0efe0281234e60c7c4f5fa812712fca50bec1b7 Mon Sep 17 00:00:00 2001 From: Eugene Syromiatnikov Date: Tue, 24 Mar 2020 05:12:09 +0100 Subject: rtc: make definitions in include/uapi/linux/rtc.h actually useful for user space BIT() macro is not defined in UAPI headers; there is, however, similarly defined _BITUL() macro present in include/uapi/linux/const.h; use it instead and include and in order to make the definitions provided in the header useful.
