68bit b592db7437 ins8250: fix cleared pending THRE interrupt ... The code notes that reading the iir register "will clear the int if this is the source of the int" and the code cleared a pending THRE interrupt if it was *pending*. This causes a lost THRE interrupt for the SWTPC 8121 terminal firmware and this locks up the TX side of the terminal. This occurred regularly when the ISR read this register upon a higher priority RX pending interrupt. The documented operation has been reinterpreted as only clearly the THRE interrupt if THRE is the highest priority interrupt and so is the pending interrupt *causing* the interrupt. This fixes that lost THRE interrupt for the SWTPC 8121 terminal.		2019-10-16 16:35:04 +11:00
