#     crypto: hisilicon/sec2 - Use atomics instead of __sync
#     
#     The use of __sync functions for atomic memory access is not
#     supported in the kernel, and can result in a link error depending
#     on configuration:
#     
#     ERROR: "__tsan_atomic32_compare_exchange_strong" [drivers/crypto/hisilicon/sec2/hisi_sec2.ko] undefined!
#     ERROR: "__tsan_atomic64_fetch_add" [drivers/crypto/hisilicon/sec2/hisi_sec2.ko] undefined!
#     
#     Use the kernel's own atomic interfaces instead. This way the
#     debugfs interface actually reads the counter atomically.
#     
#     Fixes: 416d82204df4 ("crypto: hisilicon - add HiSilicon SEC V2 driver")
