[PATCH cryptodev-2.6 1/4] crypto: cavium/nitrox - fix warnings while printing atomic64_t types

From: Srikanth Jampala
Date: Sat Sep 29 2018 - 04:20:00 EST


fix compilation warnings with nitrox_debugfs.c while printing
atomic64_t types on arm64. typecast the atomic64_read() value to u64

This issue is reported by Ard Biesheuvel

drivers/crypto/cavium/nitrox/nitrox_debugfs.c:62:30:
warning: format â%lldâ expects argument of type âlong long intâ,
but argument 3 has type âlong intâ [-Wformat=]
seq_printf(s, " Posted: %lld\n", atomic64_read(&ndev->stats.posted));
