The return type of atomic64_read() is unfortunately architecture specific, it can be 'long', 'long long', or 's64'. When it is 'long', we get a build warning: drivers/crypto/cavium/nitrox/nitrox_debugfs.c: In function 'stats_show': drivers/crypto/cavium/nitrox/nitrox_debugfs.c:62:30: error: format '%lld' expects argument of type 'long long int', but argument 3 has type 'long int' [-Werror=format=] seq_printf(s, " Posted: %lld\n", atomic64_read(&ndev->stats.posted)); ~~~^ %ld drivers/crypto/cavium/nitrox/nitrox_debugfs.c:63:33: error: format '%lld' expects argument of type 'long long int', but argument 3 has type 'long int' [-Werror=format=] seq_printf(s, " Completed: %lld\n", ~~~^ %ld drivers/crypto/cavium/nitrox/nitrox_debugfs.c:65:31: error: format '%lld' expects argument of type 'long long int', but argument 3 has type 'long int' [-Werror=format=] Add an explicit cast to 's64' to get a consistent behavior on all architectures here during compile testing.
