Subject: [PATCH][next] amd/amdgpu_ctx: Use struct_size() helper and kmalloc()
Date: Thu, 8 Oct 2020 09:34:50 -0500	[thread overview]
Message-ID: <20201008143450.GA23077@embeddedor> (raw)

Make use of the new struct_size() helper instead of the offsetof() idiom.
Also, use kmalloc() instead of kcalloc().
