Vinod Koul fb203adc28 ASoC: Intel: Skylake: Revert previous broken fix memory leak fix ... This reverts commit 87b5ed8ecb ("ASoC: Intel: Skylake: fix memory leak") as it causes regression on Skylake devices The SKL drivers can be deferred probe. The topology file based widgets can have references to topology file so this can't be freed until card is fully created, so revert this patch for now [ 66.682767] BUG: unable to handle kernel paging request at ffffc900001363fc [ 66.690735] IP: [<ffffffff806c94dd>] strnlen+0xd/0x40 [ 66.696509] PGD 16e035067 PUD 16e036067 PMD 16e038067 PTE 0 [ 66.702925] Oops: 0000 [#1] PREEMPT SMP [ 66.768390] CPU: 3 PID: 57 Comm: kworker/u16:3 Tainted: G O 4.4.0-rc7-skl #62 [ 66.778869] Hardware name: Intel Corporation Skylake Client platform [ 66.793201] Workqueue: deferwq deferred_probe_work_func [ 66.799173] task: ffff88008b700f40 ti: ffff88008b704000 task.ti: ffff88008b704000 [ 66.807692] RIP: 0010:[<ffffffff806c94dd>] [<ffffffff806c94dd>] strnlen+0xd/0x40 [ 66.816243] RSP: 0018:ffff88008b707878 EFLAGS: 00010286 [ 66.822293] RAX: ffffffff80e60a82 RBX: 000000000000000e RCX: fffffffffffffffe [ 66.830406] RDX: ffffc900001363fc RSI: ffffffffffffffff RDI: ffffc900001363fc [ 66.838520] RBP: ffff88008b707878 R08: 000000000000ffff R09: 000000000000ffff [ 66.846649] R10: 0000000000000001 R11: ffffffffa01c6368 R12: ffffc900001363fc [ 66.854765] R13: 0000000000000000 R14: 00000000ffffffff R15: 0000000000000000 [ 66.862910] FS: 0000000000000000(0000) GS:ffff88016ecc0000(0000) knlGS:0000000000000000 [ 66.872150] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 66.878696] CR2: ffffc900001363fc CR3: 0000000002c09000 CR4: 00000000003406e0 [ 66.886820] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 66.894938] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 66.903052] Stack: [ 66.905346] ffff88008b7078b0 ffffffff806cb1db 000000000000000e 0000000000000000 [ 66.913854] ffff88008b707928 ffffffffa00d1050 ffffffffa00d104e ffff88008b707918 [ 66.922353] ffffffff806ccbd6 ffff88008b707948 0000000000000046 ffff88008b707940 [ 66.930855] Call Trace: [ 66.933646] [<ffffffff806cb1db>] string.isra.4+0x3b/0xd0 [ 66.939793] [<ffffffff806ccbd6>] vsnprintf+0x116/0x540 [ 66.945742] [<ffffffff806d02f0>] kvasprintf+0x40/0x80 [ 66.951591] [<ffffffff806d0370>] kasprintf+0x40/0x50 [ 66.957359] [<ffffffffa00c085f>] dapm_create_or_share_kcontrol+0x1cf/0x300 [snd_soc_core] [ 66.966771] [<ffffffff8057dd1e>] ? __kmalloc+0x16e/0x2a0 [ 66.972931] [<ffffffffa00c0dab>] snd_soc_dapm_new_widgets+0x41b/0x4b0 [snd_soc_core] [ 66.981857] [<ffffffffa00be8c0>] ? snd_soc_dapm_add_routes+0xb0/0xd0 [snd_soc_core] [ 67.007828] [<ffffffffa00b92ed>] soc_probe_component+0x23d/0x360 [snd_soc_core] [ 67.016244] [<ffffffff80b14e69>] ? mutex_unlock+0x9/0x10 [ 67.022405] [<ffffffffa00ba02f>] snd_soc_instantiate_card+0x47f/0xd10 [snd_soc_core] [ 67.031329] [<ffffffff8049eeb2>] ? debug_mutex_init+0x32/0x40 [ 67.037973] [<ffffffffa00baa92>] snd_soc_register_card+0x1d2/0x2b0 [snd_soc_core] [ 67.046619] [<ffffffffa00c8b54>] devm_snd_soc_register_card+0x44/0x80 [snd_soc_core] [ 67.055539] [<ffffffffa01c303b>] skylake_audio_probe+0x1b/0x20 [snd_soc_skl_rt286] [ 67.064292] [<ffffffff808aa887>] platform_drv_probe+0x37/0x90 Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>		2016-01-05 11:48:39 +00:00
