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
