Stanislaw Gruszka ecb4433550 mac80211: fix suspend/resume races with unregister hw ... Do not call ->suspend, ->resume methods after we unregister wiphy. Also delete sta_clanup timer after we finish wiphy unregister to avoid this: WARNING: at lib/debugobjects.c:262 debug_print_object+0x85/0xa0() Hardware name: 6369CTO ODEBUG: free active (active state 0) object type: timer_list hint: sta_info_cleanup+0x0/0x180 [mac80211] Modules linked in: aes_i586 aes_generic fuse bridge stp llc autofs4 sunrpc cpufreq_ondemand acpi_cpufreq mperf ext2 dm_mod uinput thinkpad_acpi hwmon sg arc4 rt2800usb rt2800lib crc_ccitt rt2x00usb rt2x00lib mac80211 cfg80211 i2c_i801 iTCO_wdt iTCO_vendor_support e1000e ext4 mbcache jbd2 sd_mod crc_t10dif sr_mod cdrom yenta_socket ahci libahci pata_acpi ata_generic ata_piix i915 drm_kms_helper drm i2c_algo_bit video [last unloaded: microcode] Pid: 5663, comm: pm-hibernate Not tainted 3.1.0-rc1-wl+ #19 Call Trace: [<c0454cfd>] warn_slowpath_common+0x6d/0xa0 [<c05e05e5>] ? debug_print_object+0x85/0xa0 [<c05e05e5>] ? debug_print_object+0x85/0xa0 [<c0454dae>] warn_slowpath_fmt+0x2e/0x30 [<c05e05e5>] debug_print_object+0x85/0xa0 [<f8a808e0>] ? sta_info_alloc+0x1a0/0x1a0 [mac80211] [<c05e0bd2>] debug_check_no_obj_freed+0xe2/0x180 [<c051175b>] kfree+0x8b/0x150 [<f8a126ae>] cfg80211_dev_free+0x7e/0x90 [cfg80211] [<f8a13afd>] wiphy_dev_release+0xd/0x10 [cfg80211] [<c068d959>] device_release+0x19/0x80 [<c05d06ba>] kobject_release+0x7a/0x1c0 [<c07646a8>] ? rtnl_unlock+0x8/0x10 [<f8a13adb>] ? wiphy_resume+0x6b/0x80 [cfg80211] [<c05d0640>] ? kobject_del+0x30/0x30 [<c05d1a6d>] kref_put+0x2d/0x60 [<c05d056d>] kobject_put+0x1d/0x50 [<c08015f4>] ? mutex_lock+0x14/0x40 [<c068d60f>] put_device+0xf/0x20 [<c069716a>] dpm_resume+0xca/0x160 [<c04912bd>] hibernation_snapshot+0xcd/0x260 [<c04903df>] ? freeze_processes+0x3f/0x90 [<c049151b>] hibernate+0xcb/0x1e0 [<c048fdc0>] ? pm_async_store+0x40/0x40 [<c048fe60>] state_store+0xa0/0xb0 [<c048fdc0>] ? pm_async_store+0x40/0x40 [<c05d0200>] kobj_attr_store+0x20/0x30 [<c0575ea4>] sysfs_write_file+0x94/0xf0 [<c051e26a>] vfs_write+0x9a/0x160 [<c0575e10>] ? sysfs_open_file+0x200/0x200 [<c051e3fd>] sys_write+0x3d/0x70 [<c080959f>] sysenter_do_call+0x12/0x28 Cc: stable@kernel.org Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.
