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.
Fixes: afe9cbb1a6ad ("serial: imx: drop support for IRDA")

Hello,
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
