This is unneeded for two reasons: 1) the cpu does not write data for the device in the mapping 2) calls like ..._sync_..._for_device(..., ..._FROMDEVICE) are nonsensical, see commit 3f0fb4e85b38 ("Documentation/DMA-API-HOWTO.txt: fix misleading example") Signed-off-by: Benjamin Poirier <bpoirier@suse.com> --- drivers/staging/qlge/qlge_main.c | 12 ------------ 1 file changed, 12 deletions(-)
