Hey @Avenger-285714 - I've reviewed your changes - here's some feedback:

Overall Comments:

• The patch looks good overall. One suggestion: when copying rsrc_start and rsrc_len from hcd to shared_hcd in xhci_plat_probe(), it might be worth adding a brief inline comment explaining why these values are being shared, especially if there are any assumptions about their initialization or consistency. This can help future maintainers understand the rationale behind this resource sharing.

Here's what I looked at during the review

• 🟢 General issues: all looks good
• 🟢 Security: all looks good
• 🟢 Testing: all looks good
• 🟢 Complexity: all looks good
• 🟢 Documentation: all looks good
