From e3133b282af36665593b2802eaa591538ebe5f11 Mon Sep 17 00:00:00 2001 From: Florian Schilhabel Date: Sat, 6 Mar 2010 20:44:33 +0100 Subject: [PATCH] staging: rtl8192su: move to EEPROM_93CX this is basically a port of Larry Fingers Patch for rtl8187se to rtl8192su. also removed some dead code. plus cosmetics.
