This is giving a warning. Shouldn't v1 be kept as it is here? Please refer to "net: stmmac: platform: use optional clk/reset get APIs" [1] which modified error handling for plat->stmmac_rst. PTR_ERR() would then be called by the parent function on the returned value of ret. [1]: https://lore.kernel.org/netdev/20201112092606.5173aa6f@xhacker.debian/ Thanks, Matthew
