From 47ac26833663da51e7ac801db4badc2880c682c3 Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Sun, 17 Feb 2008 17:35:55 +0100 Subject: rt2x00: Fix hw mode registration with mac80211. The supported_bands field of struct hw_mode_spec now represents a bitfield, so bitfield operators need to be tested with when setting the band data. The current code generates the following warning: [176624.986244] WARNING: at /usr/local/src/incoming/compat-wireless-2.6/net/wireless/core.c:269 wiphy_register() [176624.986249] Pid: 12548, comm: modprobe Tainted: P 2.6.24.2#4 [176624.986251] [176624.986251] Call Trace: [176624.986277] [] :cfg80211:wiphy_register+0x17f/0x1a0 [176624.986282] [] :rt61pci:rt61pci_eepromregister_write+0x0/0x80 [176624.986302] [] :mac80211:ieee80211_register_hw+0x2c/0x2b0 [176624.986310] [] :rt2x00lib:rt2x00lib_probe_dev+0x350/0x3f0 [176624.986318] [] :rt2x00pci:rt2x00pci_probe+0x149/0x200 [176624.986325] [] pci_device_probe+0xf8/0x170 [176624.986331] [] driver_probe_device+0x9c/0x1c0 [176624.986335] [] __driver_attach+0x0/0xb0 [176624.986337] [] __driver_attach+0xa5/0xb0 [176624.986341] [] bus_for_each_dev+0x4d/0x80 [176624.986347] [] bus_add_driver+0xac/0x210 [176624.986351] [] __pci_register_driver+0x73/0xc0 [176624.986357] [] sys_init_module+0x18e/0x1a20 [176624.986374] [] system_call+0x7e/0x83 Signed-off-by: Gertjan van Wingerde Signed-off-by: Ivo van Doorn Signed-off-by: John W.
