[PATCH 2/2] drivers/tty/serial: use correct type for dma_map/unmap
From: Wolfram Sang <hidden>
Date: 2014-07-21 09:43:29
Also in:
linux-serial, lkml
Subsystem:
microchip at91 serial driver, the rest, tty layer and serial drivers · Maintainers:
Richard Genoud, Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby
dma_{un}map_* uses 'enum dma_data_direction' not 'enum dma_transfer_direction'.
