+Subject: [PATCH 3/9] rt2x00: Don't free register information on suspend
+
+After suspend & resume the rt2x00 devices won't wakeup
+anymore due to a broken register information setup.
+The most important problem is the release of the EEPROM
+buffer which is completely cleared and never read again
+after the suspend.
