Subject: [PATCH 1/1] RDMA/uverbs: Fix typo of sizeof argument
Git-commit: c489800e0d48097fc6afebd862c6afa039110a36
Patch-mainline: v6.6-rc5
References: git-fixes
Since size of 'hdr' pointer and '*hdr' structure is equal on 64-bit
machines issue probably didn't cause any wrong behavior. But anyway,
fixing of typo is required.
Fixes: da0f60df7bd5 ("RDMA/uverbs: Prohibit write() calls with too small buffers")
