[ Upstream commit be551ee1574280ef8afbf7c271212ac3e38933ef ] Relax DEVX access upon modify commands to be UVERBS_ACCESS_READ. The kernel doesn't need to protect what firmware protects, or what causes no damage to anyone but the user. As firmware needs to protect itself from parallel access to the same object, don't block parallel modify/query commands on the same object in the kernel side. This change will allow user space application to run parallel updates to different entries in the same bulk object.
