From 9d490b4ee4d7d495a4f4908ea998d2a7355e0807 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Tue, 23 Aug 2016 12:38:56 -0400 Subject: net: dsa: rename switch operations structure Now that the dsa_switch_driver structure contains only function pointers as it is supposed to, rename it to the more appropriate dsa_switch_ops, uniformly to any other operations structure in the kernel. No functional changes here, basically just the result of something like: s/dsa_switch_driver *drv/dsa_switch_ops *ops/g However keep the {un,}register_switch_driver functions and their dsa_switch_drivers list as is, since they represent the -- likely to be deprecated soon -- legacy DSA registration framework. In the meantime, also fix the following checks from checkpatch.pl to make it happy with this patch: CHECK: Comparison to NULL could be written "!ops" #403: FILE: net/dsa/dsa.c:470: + if (ops == NULL) { CHECK: Comparison to NULL could be written "ds->ops->get_strings" #773: FILE: net/dsa/slave.c:697: + if (ds->ops->get_strings != NULL) CHECK: Comparison to NULL could be written "ds->ops->get_ethtool_stats" #824: FILE: net/dsa/slave.c:785: + if (ds->ops->get_ethtool_stats != NULL) CHECK: Comparison to NULL could be written "ds->ops->get_sset_count" #835: FILE: net/dsa/slave.c:798: + if (ds->ops->get_sset_count != NULL) total: 0 errors, 0 warnings, 4 checks, 784 lines checked Signed-off-by: Vivien Didelot Acked-by: Florian Fainelli Signed-off-by: David S.
