[RFC 23/24] SERIAL: omap: move driver private definitions and structures to driver
Russell King
rmk+kernel at arm.linux.org.uk
Sat Oct 6 08:46:48 EDT 2012
struct uart_omap_port and struct uart_omap_dma, and associated
definitions are private to the driver, so there's no point them sitting
in an include file under arch/arm. Move them into the driver itself.
