H A D | vmxnet3_drv.c | fb5c6cfa Fri Oct 14 16:01:20 CDT 2016 Alexey Khoroshilov <khoroshilov@ispras.ru> vmxnet3: avoid assumption about invalid dma_pa in vmxnet3_set_mc()
vmxnet3_set_mc() checks new_table_pa returned by dma_map_single() with dma_mapping_error(), but even there it assumes zero is invalid pa (it assumes dma_mapping_error(...,0) returns true if new_table is NULL).
The patch adds an explicit variable to track status of new_table_pa.
Found by Linux Driver Verification project (linuxtesting.org).
v2: use "bool" and "true"/"false" for boolean variables. Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru> Signed-off-by: David S.
