Vasanthakumar Thiagarajan 068a4633bf ath6kl: Fix kernel panic while receiving fwlog during boot ... "ath6kl: Defer wiphy and netdev registration till the end of ath6kl_core_init()" causes kernel panic by accessing the unallocated debug resources during boot time. To fix this, split the debug initialization funtion into two, one initializes the debug resource and the other takes care of debugfs initialization. When this issue shows up the kernel crash dump would look like ath6kl_debug_fwlog_event+0x9c/0x10a [<c10666c9>] register_lock_class+0x57/0x288 [<c1065cd3>] ? trace_hardirqs_on+0xb/0xd [<f801f4c9>] ? ath6kl_debug_fwlog_event+0x9c/0x10a [<c1066a8a>] __lock_acquire+0x96/0xbe5 [<c106007b>] ? alarmtimer_suspend+0x80/0x127 [<c10258da>] ? vprintk+0x394/0x3b1 [<f801f4c9>] ? ath6kl_debug_fwlog_event+0x9c/0x10a [<c10676b3>] lock_acquire+0xda/0xf9 [<f801f4c9>] ? ath6kl_debug_fwlog_event+0x9c/0x10a [<c1532ce3>] _raw_spin_lock+0x28/0x58 [<f801f4c9>] ? ath6kl_debug_fwlog_event+0x9c/0x10a [<f801f4c9>] ath6kl_debug_fwlog_event+0x9c/0x10a [<f80310a4>] ath6kl_wmi_control_rx+0x69d/0xb50 [ath6kl_core] [<f802d2e1>] ? ath6kl_rx+0x3c/0x839 [ath6kl_core] [<f802d35d>] ath6kl_rx+0xb8/0x839 [ath6kl_core] [<c104b81e>] ? local_clock+0x2d/0x4e [<c102a0af>] ? _local_bh_enable_ip+0x94/0x98 [<f802bfc0>] ? ath6kl_alloc_amsdu_rxbuf+0xb7/0xb7 [<f8023b28>] ath6kl_htc_rxmsg_pending_handler+0x891/0x988 [ath6kl_core] [<f802bf00>] ? ath6kl_refill_amsdu_rxbufs+0x89/0x92 [<f802d2a5>] ? aggr_timeout+0xed/0xed [ath6kl_core] [<f802bfc0>] ? ath6kl_alloc_amsdu_rxbuf+0xb7/0xb7 [<f802c420>] ? ath6kl_tx_complete+0x376/0x376 [ath6kl_core] [<f8020e92>] ath6kl_hif_intr_bh_handler+0xf7/0x33e [<c138ab00>] ? mmc_host_disable+0x15/0x3a [<f8123b5c>] ath6kl_sdio_irq_handler+0x3c/0x90 [ath6kl_sdio] [<c1392f56>] sdio_irq_thread+0xb6/0x29c [<c1392ea0>] ? sdio_claim_irq+0x1cb/0x1cb [<c103d4c0>] kthread+0x67/0x6c [<c103d459>] ? __init_kthread_worker+0x42/0x42 [<c153903a>] kernel_thread_helper+0x6/0xd BUG: unable to handle kernel NULL pointer dereference at EIP: [<f801f4d4>] ath6kl_debug_fwlog_event+0xa7/0x10a kvalo: rename new function to ath6kl_debug_init_fs() and add a comment why it's needed Reported-by: Kalle Valo <kvalo@qca.qualcomm.com> Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>		2012-03-06 17:53:54 +02:00
