Subject: serial: 8250_omap: Remove RTS clear
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0abcc6df070687816b0ca0aefc3d64c62773063c;p=linux-beck.git

serial: 8250_omap: Remove RTS clear

Clearing UART_MCR_RTS or UART_MCR_XONANY is unnecessary; these bits
are never set in the shadow mcr. The RTS clear is especially confusing.
