+
+Remove a leftover assert for mac_reset line in mtk_pcie_en7581_power_up().
+
+This is not harmful since EN7581 does not requires mac_reset and
+mac_reset is not defined in EN7581 device tree.

-Subject: [PATCH] PCI: mediatek-gen3: Remove mac_reset assert leftover for
- Airoha EN7581 SoC.
-
-Remove a leftover assert for mac_reset line in mtk_pcie_en7581_power_up().
-This is not armful since EN7581 does not requires mac_reset and
-mac_reset is not defined in EN7581 device tree.
