  "message": "Revert \"serial/8250_pci: setup-quirk workaround for the kt serial controller\"\n\nThis reverts commit 448ac154c957c4580531fa0c8f2045816fe2f0e7.\n\nThe semantic of UPF_IIR_ONCE is only guaranteed to workaround the race\ncondition in the kt serial\u0027s iir register if the only source of\ninterrupts is THRE (fifo-empty) events.  An modem status event at the\nwrong time can again cause an iir read to drop the \u0027empty\u0027 status\nleading to a hang.  So, revert this in preparation for using the\nexisting \"I don\u0027t trust my iir register\" workaround in the 8250 core\n(UART_BUG_THRE).\n\n[stable: 3.3.x]\nCc: stable \u003cstable@vger.kernel.org\u003e\nAcked-by: Alan Cox \u003calan@linux.intel.com\u003e\nCc: Sudhakar Mamillapalli \u003csudhakar@fb.com\u003e\nReported-by: Nhan H Mai \u003cnhan.h.mai@intel.com\u003e\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
