commit 7e620984b62532783912312e334f3c48cdacbd5d upstream.

Back in 2015 when irda was dropped from the driver imx1 was broken. This change reintroduces the support for the third interrupt of the UART.

this is a backport of 7e620984b62532783912312e334f3c48cdacbd5d to v4.14.y that misses

9d1a50a2cceb (serial: imx: consistently use imx_uart_ as prefix for all functions)

which changed many function names. So the old function name has to be used.

Best regards Uwe
