sysfs: use sysfs_bin_attr_init in firmware class driver
Annotate dynamic sysfs attribute in fw_setup_device(). This gets rid of the following lockdep warning: bnx2 0000:08:00.0: firmware: requesting bnx2/bnx2-mips-06-5.0.0.j6.fw BUG: key ffff880008293470 not in .data! ------------[ cut here ]------------ WARNING: at kernel/lockdep.c:2706 lockdep_init_map+0x562/0x620() Modules linked in: bnx2(+) sg tpm_bios floppy rtc_lib usb_storage i2c_piix4 joydev button container shpchp i2c_core sr_mod cdrom pci_hotplug usbhid hid ohci_hcd ehci_hcd sd_mod usbcore edd ext3 mbcache jbd fan ata_generic sata_svw pata_serverworks libata scsi_mod thermal processor Pid: 1915, comm: work_for_cpu Not tainted 2.6.34-rc1-default #81 Call Trace: [<ffffffff8107c1d2>] ? lockdep_init_map+0x562/0x620 [<ffffffff81049fd8>] warn_slowpath_common+0x78/0xd0 [<ffffffff8104a03f>] warn_slowpath_null+0xf/0x20 [<ffffffff8107c1d2>] lockdep_init_map+0x562/0x620 [<ffffffff8117a236>] ? sysfs_new_dirent+0x76/0x120 [<ffffffff8126edb2>] ? put_device+0x12/0x20 [<ffffffff811797cc>] sysfs_add_file_mode+0x6c/0xd0 [<ffffffff8117983c>] sysfs_add_file+0xc/0x10 [<ffffffff8117bf61>] sysfs_create_bin_file+0x21/0x30 [<ffffffff81279c61>] _request_firmware+0x2f1/0x650 [<ffffffff8127a04e>] request_firmware+0xe/0x10 [<ffffffffa01ec19e>] bnx2_init_one+0x8f5/0x177e [bnx2] [<ffffffff81389eab>] ? _raw_spin_unlock_irq+0x2b/0x40 [<ffffffff81040ed9>] ? finish_task_switch+0x69/0x100 [<ffffffff81040e70>] ? finish_task_switch+0x0/0x100 [<ffffffff81064b40>] ? do_work_for_cpu+0x0/0x30 [<ffffffff811e6302>] local_pci_probe+0x12/0x20 [<ffffffff81064b53>] do_work_for_cpu+0x13/0x30 [<ffffffff81064b40>] ? do_work_for_cpu+0x0/0x30 [<ffffffff81068c56>] kthread+0x96/0xa0 [<ffffffff81003e64>] kernel_thread_helper+0x4/0x10 [<ffffffff8138a350>] ? restore_args+0x0/0x30 [<ffffffff81068bc0>] ? kthread+0x0/0xa0 [<ffffffff81003e60>] ? kernel_thread_helper+0x0/0x10 ---[ end trace a2ecee9c9602d195 ]--- Cc: Eric W.
