Subject: [PATCH 09/21] can: netlink: remove useless check in can_tdc_changelink()
Date: Wed, 03 Sep 2025 17:50:08 +0900 [thread overview]
Message-ID: <20250903-canxl-netlink-prep-v1-9-904bd6037cd9@kernel.org> (raw)
In-Reply-To: <20250903-canxl-netlink-prep-v1-0-904bd6037cd9@kernel.org>
can_tdc_changelink() return -EOPNOTSUPP under this condition:
!tdc_const || !can_fd_tdc_is_enabled(priv)
But this function is only called if the data[IFLA_CAN_TDC] parameters
are provided. At this point, can_validate_tdc() already checked that
either of the tdc auto or tdc manual control modes were provided, that
is to say, can_fd_tdc_is_enabled(priv) must be true.
Because the right hand operand of this condition is always true,
remove it.
