Ronald WahlandGreg Kroah-Hartman 70dc9a482f serial: 8250: 8250_omap: Clear UART_HAS_RHR_IT_DIS bit
commit 8973ab7a24 upstream.

This fixes commit 439c7183e5 ("serial: 8250: 8250_omap: Disable RX
interrupt after DMA enable") which unfortunately set the
UART_HAS_RHR_IT_DIS bit in the UART_OMAP_IER2 register and never
cleared it.
