Hi Shawn,
you're loosing the original author. Your can override the patch-author (away from the mail sender) via a "From:" line at the top of the commit message, like: ------ From: Boojin Kim <[email protected]> This patch adds to support burst mode for dev-to-mem and mem-to-dev transmit. ... ------ > This patch adds to support burst mode for dev-to-mem and > mem-to-dev transmit. > > Signed-off-by: Boojin Kim <[email protected]> > Signed-off-by: Addy Ke <[email protected]> > Signed-off-by: Shawn Lin <[email protected]> > cc: Heiko Stuebner <[email protected]> > cc: Doug Anderson <[email protected]> > cc: Olof Johansson <[email protected]> > Reviewed-and-tested-by: Sonny Rao <[email protected]> > > --- > > drivers/dma/pl330.c | 18 ++++++++++++------ > 1 file changed, 12 insertions(+), 6 deletions(-) > > diff --git a/drivers/dma/pl330.c b/drivers/dma/pl330.c > index ecab4ea0..0d544d2 100644 > --- a/drivers/dma/pl330.c > +++ b/drivers/dma/pl330.c > @@ -1141,10 +1141,13 @@ static inline int _ldst_devtomem(unsigned dry_run, > u8 buf[], const struct _xfer_spec *pxs, int cyc) > { > int off = 0; > + enum pl330_cond cond; > + > + cond = (pxs->desc->rqcfg.brst_len == 1) ?
