From: Tomoya MORINAGA <redacted> PCH_DMA is not always enabled when a user uses PCH_UART. Since overhead of DMA is not small, in case of low frequent communication, without DMA is better. Thus, "select PCH_DMA" and DMADEVICES are unnecessary Signed-off-by: Tomoya MORINAGA <redacted> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> --- drivers/tty/serial/Kconfig | 5 ++--- 1 files changed, 2 insertions(+), 3 deletions(-)
