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.
