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().
Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org>
