  "message": "nfc: nci: clear NCI_DATA_EXCHANGE before calling completion callback\n\n[ Upstream commit 0efdc02f4f6d52f8ca5d5889560f325a836ce0a8 ]\n\nMove clear_bit(NCI_DATA_EXCHANGE) before invoking the data exchange\ncallback in nci_data_exchange_complete().\n\nThe callback (e.g. rawsock_data_exchange_complete) may immediately\nschedule another data exchange via schedule_work(tx_work).  On a\nmulti-CPU system, tx_work can run and reach nci_transceive() before\nthe current nci_data_exchange_complete() clears the flag, causing\ntest_and_set_bit(NCI_DATA_EXCHANGE) to return -EBUSY and the new\ntransfer to fail.\n\nThis causes intermittent flakes in nci/nci_dev in NIPA:\n\n  # #  RUN           NCI.NCI1_0.t4t_tag_read ...\n  # # t4t_tag_read: Test terminated by timeout\n  # #          FAIL  NCI.NCI1_0.t4t_tag_read\n  # not ok 3 NCI.NCI1_0.t4t_tag_read\n\nFixes: 38f04c6b1b68 (\"NFC: protect nci_data_exchange transactions\")\nReviewed-by: Joe Damato \u003cjoe@dama.to\u003e\nLink: https://patch.msgid.link/20260303162346.2071888-5-kuba@kernel.org\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\nSigned-off-by: Sasha Levin \u003csashal@kernel.org\u003e\n",
