From 117839bd1251dc654938c529c95c7611ac260351 Mon Sep 17 00:00:00 2001 From: Pavel Roskin Date: Sun, 2 Aug 2009 14:30:02 -0400 Subject: [PATCH] rt61pci: fix module reloading Unloading rt61pci can leave the device in such state that reloading rt61pci would fail to reinitialize it. Bogus data would be read from the EEPROM and the RF version won't be recognized. It appears that unloading rt61pci with power saving enabled would have such effect. To initialize the device properly, SOFT_RESET_CSR should be set to the same value as rt61pci_config_ps() uses to wake up the device. Signed-off-by: Pavel Roskin Signed-off-by: John W.
