From: Vincent Mailhol Date: Tue, 12 Nov 2024 16:50:20 +0000 (+0900) Subject: can: netlink: can_changelink(): rename tdc_mask into fd_tdc_flag_provided X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=527b99f44def0decc39cef434fd26cdaef74d31c;p=thirdparty%2Flinux.git can: netlink: can_changelink(): rename tdc_mask into fd_tdc_flag_provided The only purpose of the tdc_mask variable is to check whether or not any tdc flags (CAN_CTRLMODE_TDC_{AUTO,MANUAL}) were provided. At this point, the actual value of the flags do no matter any more because these can be deduced from some other information. Rename the tdc_mask variable into fd_tdc_flag_provided to make this more explicit. Note that the fd_ prefix is added in preparation of the introduction of CAN XL.
