Subject: [PATCH net-next v3 07/18] net: stmmac: clean up stmmac_disable_eee_mode()
Date: Tue, 07 Jan 2025 16:29:02 +0000 [thread overview]
Message-ID: <E1tVCRy-007Y3Z-Ri@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <Z31V9O8SATRbu2L3@shell.armlinux.org.uk>
stmmac_disable_eee_mode() is now only called from stmmac_xmit() when
both priv->tx_path_in_lpi_mode and priv->eee_sw_timer_en are true.
Therefore:
if (!priv->eee_sw_timer_en)
in stmmac_disable_eee_mode() will never be true, so this is dead code.
Remove it, and rename the function to indicate that it now only deals
with software based EEE mode.
