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'

[-Werror=format=]
seq_printf(s, " Posted: %lld\n", atomic64_read(&ndev->stats.posted));

Add an explicit cast to 's64' to get a consistent behavior on all
architectures here during compile testing.
