Shuicheng Lin 02dc6cf640 drm/xe/nvm: Manage nvm aux cleanup with devres [ Upstream commit `2da8fbb8f1` ] Move nvm teardown to a devm-managed action registered from xe_nvm_init(). This ensures the auxiliary NVM device is deleted on probe failure and device detach without requiring explicit calls from remove paths. As part of this, drop xe_nvm_fini() from xe_device_remove() and from the survivability sysfs teardown, and remove the public xe_nvm_fini() API from the header. This is to fix below warn message when there is probe failure after xe_nvm_init(), then xe_device_probe() is called again: " [ 207.318152] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:01.0/0000:01:00.0/0000:02:01.0/0000:03:00.0/xe.nvm.768' [ 207.318157] CPU: 5 UID: 0 PID: 10261 Comm: modprobe Tainted: G B W 6.19.0-rc2-lgci-xe-kernel+ #223 PREEMPT(voluntary) [ 207.318160] Tainted: [B]=BAD_PAGE, [W]=WARN [ 207.318161] Hardware name: ASUS System Product Name/PRIME Z790-P WIFI, BIOS 0812 02/24/2023 [ 207.318163] Call Trace: [ 207.318163] <TASK> [ 207.318165] dump_stack_lvl+0xa0/0xc0 [ 207.318170] dump_stack+0x10/0x20 [ 207.318171] sysfs_warn_dup+0xd5/0x110 [ 207.318175] sysfs_create_dir_ns+0x1f6/0x280 [ 207.318177] ? __pfx_sysfs_create_dir_ns+0x10/0x10 [ 207.318179] ? lock_acquire+0x1a4/0x2e0 [ 207.318182] ? __kasan_check_read+0x11/0x20 [ 207.318185] ? do_raw_spin_unlock+0x5c/0x240 [ 207.318187] kobject_add_internal+0x28d/0x8e0 [ 207.318189] kobject_add+0x11f/0x1f0 [ 207.318191] ? __pfx_kobject_add+0x10/0x10 [ 207.318193] ? lockdep_init_map_type+0x4b/0x230 [ 207.318195] ? get_device_parent.isra.0+0x43/0x4c0 [ 207.318197] ? kobject_get+0x55/0xf0 [ 207.318199] device_add+0x2d7/0x1500 [ 207.318201] ? __pfx_device_add+0x10/0x10 [ 207.318203] ? lockdep_init_map_type+0x4b/0x230 [ 207.318205] __auxiliary_device_add+0x99/0x140 [ 207.318208] xe_nvm_init+0x7a2/0xef0 [xe] [ 207.318333] ? xe_devcoredump_init+0x80/0x110 [xe] [ 207.318452] ? __devm_add_action+0x82/0xc0 [ 207.318454] ? fs_reclaim_release+0xc0/0x110 [ 207.318457] xe_device_probe+0x17dd/0x2c40 [xe] [ 207.318574] ? __pfx___drm_dev_dbg+0x10/0x10 [ 207.318576] ? add_dr+0x180/0x220 [ 207.318579] ? __pfx___drmm_mutex_release+0x10/0x10 [ 207.318582] ? __pfx_xe_device_probe+0x10/0x10 [xe] [ 207.318697] ? xe_pm_init_early+0x33a/0x410 [xe] [ 207.318850] xe_pci_probe+0x936/0x1250 [xe] [ 207.318999] ? lock_acquire+0x1a4/0x2e0 [ 207.319003] ? __pfx_xe_pci_probe+0x10/0x10 [xe] [ 207.319151] local_pci_probe+0xe6/0x1a0 [ 207.319154] pci_device_probe+0x523/0x840 [ 207.319157] ? __pfx_pci_device_probe+0x10/0x10 [ 207.319159] ? sysfs_do_create_link_sd.isra.0+0x8c/0x110 [ 207.319162] ? sysfs_create_link+0x48/0xc0 ...

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.
