Subject[PATCH v2 11/13] drivers/staging/rtl8188eu: convert stats to use seqnum_ops
Date
Sequence Number api provides interfaces for unsigned atomic up counters
leveraging atomic_t and atomic64_t ops underneath. Convert it to use
seqnum_ops.

atomic_t variables used for stats are atomic counters. Convert them to
use seqnum_ops.
