IB/qib: Remove redundant assignment to ret
Variable 'ret' is set to zero but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed. Clean up the following clang-analyzer warning: drivers/infiniband/hw/qib/qib_sd7220.c:690:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores] Link: https://lore.kernel.org/r/[email protected] Reported-by: Abaci Robot <[email protected]> Signed-off-by: Yang Li <[email protected]> Signed-off-by: Jason Gunthorpe <[email protected]>
