From 05b606b8845213092b50a855ecf7211caa7c82fa Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Wed, 7 Jun 2023 12:58:49 +0100 Subject: net: pcs: lynx: change lynx_pcs_create() to return error-pointers Change lynx_pcs_create() to return an error-pointer on failure to allocate memory, rather than returning NULL. This allows the removal of the conversion in lynx_pcs_create_fwnode() and lynx_pcs_create_mdiodev().
