The function adf_gen4_get_vf2pf_sources() computes a mask which is stored in a variable which is returned and not used. Remove superfluous assignment of variable. This is to fix the following warning when compiling the QAT driver with clang scan-build: drivers/crypto/qat/qat_common/adf_gen4_pfvf.c:46:9: warning: Although the value stored to 'sou' is used in the enclosing expression, the value is never actually read from 'sou' [deadcode.DeadStores] return sou &= ~mask; ^ ~~~~~ Fixes: 5901b4af6e07 ("crypto: qat - fix access to PFVF interrupt registers for GEN4") Signed-off-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> --- drivers/crypto/qat/qat_common/adf_gen4_pfvf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
