swiotlb: silent unwanted warning "buffer is full"
If DMA_ATTR_NO_WARN is passed to swiotlb_alloc_buffer(), it should be passed further down to swiotlb_tbl_map_single(). Otherwise we escape half of the warnings but still log the other half. This is one of the multiple causes of spurious warnings reported at: https://bugs.freedesktop.org/show_bug.cgi?id=104082 Signed-off-by: Jean Delvare <jdelvare@suse.de> Fixes: 0176adb00406 ("swiotlb: refactor coherent buffer allocation") Cc: Christoph Hellwig <hch@lst.de> Cc: Christian König <christian.koenig@amd.com> Cc: Michel Dänzer <michel@daenzer.net> Cc: Takashi Iwai <tiwai@suse.de> Cc: stable@vger.kernel.org # v4.16
