| |
Variable result is being assigned a value from a calculation however the variable is never read, so this redundant variable can be removed.
Cleans up the following clang-analyzer warning:
drivers/net/ethernet/chelsio/inline_crypto/ch_ktls/chcr_ktls.c:1488:2: warning: Value stored to 'pos' is never read [clang-analyzer-deadcode.DeadStores].
drivers/net/ethernet/chelsio/inline_crypto/ch_ktls/chcr_ktls.c:876:3: warning: Value stored to 'pos' is never read [clang-analyzer-deadcode.DeadStores].
drivers/net/ethernet/chelsio/inline_crypto/ch_ktls/chcr_ktls.c:36:3: warning: Value stored to 'start' is never read [clang-analyzer-deadcode.DeadStores].
