----------------------------
What: corgikbd, spitzkbd, tosakbd driver
When: 2.6.35
Files: drivers/input/keyboard/{corgi,spitz,tosa}kbd.c
......@@ -608,3 +607,24 @@ Why: Useful in 2003, implementation is a hack.
Generally invoked by accident today.
Seen as doing more harm than good.
Who: Len Brown <len.brown@intel.com>
----------------------------
What: iwlwifi 50XX module parameters
When: 2.6.40
Why: The "..50" modules parameters were used to configure 5000 series and
up devices; different set of module parameters also available for 4965
with same functionalities. Consolidate both set into single place
in drivers/net/wireless/iwlwifi/iwl-agn.c
Who: Wey-Yi Guy <wey-yi.w.guy@intel.com>
----------------------------
What: iwl4965 alias support
When: 2.6.40
Why: Internal alias support has been present in module-init-tools for some
time, the MODULE_ALIAS("iwl4965") boilerplate aliases can be removed
with no impact.
