Subject: [PATCH 05/32] hinic: Avoid some over memory allocation
Git-commit: 15d221d0c345b76947911a3ac91897ffe2f1cc4e
References: git-fixes
Patch-mainline: v5.19-rc1
'prod_idx' (atomic_t) is larger than 'shadow_idx' (u16), so some memory is
over-allocated.
Fixes: b15a9f37be2b ("net-next/hinic: Add wq")
