It's being removed from other drivers too.  Just remove\nit.  This leaves hwrng, which is actually used.\n\nTagging with 'Cc stable' due to the bugs that this removes:\n\n  - xtrng_trng_generate() sometimes returned success even when it didn't\n    fill in all the bytes.\n\n  - It was possible for xtrng_trng_generate() and\n    xtrng_hwrng_trng_read() to run concurrently and interfere with each\n    other, as the locking code in xtrng_hwrng_trng_read() was broken.","published":"2026-09-04T17:16:59.000Z","lastModified":"2026-09-04T17:16:59.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00206,"percentile":0.10615,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
