Cristian Ciocaltea 77dc0140ea ASoC: nau8821: Fixup nau8821_enable_jack_detect() [ Upstream commit `70237853ed` ] The nau8821_enable_jack_detect() function was supposed to allow enabling or disabling jack events reporting. However, once enabled, any subsequent invocation would fail and the following splat is shown: [ 3136.996771] Hardware name: Valve Jupiter/Jupiter, BIOS F7A0131 01/30/2024 [ 3136.996773] Workqueue: events_unbound deferred_probe_work_func [ 3136.996780] Call Trace: [ 3136.996782] <TASK> [ 3136.996787] dump_stack_lvl+0x6e/0xa0 [ 3136.996796] __setup_irq.cold+0x9c/0xce [ 3136.996803] ? __pfx_irq_default_primary_handler+0x10/0x10 [ 3136.996812] ? __pfx_nau8821_interrupt+0x10/0x10 [snd_soc_nau8821] [ 3136.996825] request_threaded_irq+0xd9/0x160 [ 3136.996853] devm_request_threaded_irq+0x71/0xd0 [ 3136.996859] ? __pfx_nau8821_interrupt+0x10/0x10 [snd_soc_nau8821] [ 3136.996882] nau8821_enable_jack_detect+0xa5/0xc0 [snd_soc_nau8821] [ 3136.996901] acp5x_8821_init+0x8d/0xa0 [snd_soc_acp5x_mach] [ 3136.996917] snd_soc_link_init+0x25/0x50 [snd_soc_core] [ 3136.996958] snd_soc_bind_card+0x615/0xd00 [snd_soc_core] [ 3136.997026] snd_soc_register_card+0x1b2/0x1c0 [snd_soc_core] [ 3136.997064] devm_snd_soc_register_card+0x47/0x90 [snd_soc_core] [ 3136.997108] acp5x_probe+0x72/0xb0 [snd_soc_acp5x_mach] [...] [ 3136.997508] nau8821 i2c-NVTN2020:00: Cannot request irq 58 (-16) Introduce jdet_active flag to driver data structure and use it to provide one-time initialization of the jack detection work queue and related interrupt line. Note this is also a prerequisite for additional fixes around module unloading and suspend handling.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
