Subject: [PATCH v4 0/4] Miscellaneous fixes for pci subsystem

Miscellaneous fixes for pci subsystem

Changes in v4:
- Remove the architecture-specific #ifdef to apply the alignment
  check for all platforms (including x86), as device registers are
  naturally aligned anyway.
- Fix a potential issue in proc_bus_pci_read() to make it consistent
  with proc_bus_pci_write(), as suggested by Ilpo Järvinen.
- Link to v3: https://lore.kernel.org/linux-pci/20260108015944.3520719-1-duziming2@huawei.com/

Changes in v3:
- Check *ppos before assign it to pos.
- Link to v2: https://lore.kernel.org/linux-pci/20251224092721.2034529-1-duziming2@huawei.com/

Changes in v2:
- Correct grammer and indentation.
- Remove unrelated stack traces from the commit message.
- Modify the handling of pos by adding a non-negative check to ensure
  that the input value is valid.
- Use the existing IS_ALIGNED macro and ensure that after modification,
  other cases still retuen -EINVAL as before.
- Link to v1: https://lore.kernel.org/linux-pci/20251216083912.758219-1-duziming2@huawei.com/
