Revert "ALSA: hda: Add support for Loongson 7A1000 controller"
This reverts commit 61eee4a7fc40 ("ALSA: hda: Add support for Loongson 7A1000 controller") to fix the following error on the Loongson LS7A platform: rcu: INFO: rcu_preempt self-detected stall on CPU <SNIP> NMI backtrace for cpu 0 CPU: 0 PID: 68 Comm: kworker/0:2 Not tainted 5.8.0+ #3 Hardware name: , BIOS Workqueue: events azx_probe_work [snd_hda_intel] <SNIP> Call Trace: [<ffffffff80211a64>] show_stack+0x9c/0x130 [<ffffffff8065a740>] dump_stack+0xb0/0xf0 [<ffffffff80665774>] nmi_cpu_backtrace+0x134/0x140 [<ffffffff80665910>] nmi_trigger_cpumask_backtrace+0x190/0x200 [<ffffffff802b1abc>] rcu_dump_cpu_stacks+0x12c/0x190 [<ffffffff802b08cc>] rcu_sched_clock_irq+0xa2c/0xfc8 [<ffffffff802b91d4>] update_process_times+0x2c/0xb8 [<ffffffff802cad80>] tick_sched_timer+0x40/0xb8 [<ffffffff802ba5f0>] __hrtimer_run_queues+0x118/0x1d0 [<ffffffff802bab74>] hrtimer_interrupt+0x12c/0x2d8 [<ffffffff8021547c>] c0_compare_interrupt+0x74/0xa0 [<ffffffff80296bd0>] __handle_irq_event_percpu+0xa8/0x198 [<ffffffff80296cf0>] handle_irq_event_percpu+0x30/0x90 [<ffffffff8029d958>] handle_percpu_irq+0x88/0xb8 [<ffffffff80296124>] generic_handle_irq+0x44/0x60 [<ffffffff80b3cfd0>] do_IRQ+0x18/0x28 [<ffffffff8067ace4>] plat_irq_dispatch+0x64/0x100 [<ffffffff80209a20>] handle_int+0x140/0x14c [<ffffffff802402e8>] irq_exit+0xf8/0x100 Because AZX_DRIVER_GENERIC can not work well for Loongson LS7A HDA controller, it needs some workarounds which are not merged into the upstream kernel at this time, so it should revert this patch now.
