Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [High] Fixing the HPA quirk matching causes these drives to lose their required ATA_QUIRK_WD_BROKEN_LPM flag due to early loop termination.
- [Low] Malformed Fixes and Signed-off-by tags in the commit message.

libata: Fix HPA horkage to target whole model series not just a few devices

This commit updates the __ata_dev_quirks table to target an entire model
series for the ATA_QUIRK_BROKEN_HPA quirk instead of specific device serial
numbers. It resolves an issue where the HPA horkage was not applied to all
affected drives.

[Severity: Low]
Does this commit message violate formatting guidelines?

Automated tooling might fail to parse the Fixes tag due to the invalid
backslash escape instead of an opening quote, and the Signed-off-by tag is
missing angle brackets around the email address.

[Severity: High]
Does this change cause these drives to lose their required
ATA_QUIRK_WD_BROKEN_LPM flag?

During device initialization, ata_dev_quirks() iterates through the
__ata_dev_quirks table and returns immediately upon the first match. By fixing
the firmware string to correctly match these devices here, the function will
now exit early and skip the subsequent ATA_QUIRK_WD_BROKEN_LPM entry that
these drives previously relied on:

    { "WDC WD3200JD-*",     NULL,   ATA_QUIRK_WD_BROKEN_LPM },

Without this flag, Link Power Management issues on these specific WD drives
could cause command timeouts, NCQ errors, and potential drive dropouts.

As indicated by Sashiko, this is not formatted correctly.

And this one as well.

Also please write a proper commit message that explains what you are changing.
Because saying "target whole model series" in the commit title but changing the
quirk entries to still have a FW revision does not do that at all.
