Kees Cook	0ed2dd03b9	treewide: Use struct_size() for devm_kmalloc() and friends Replaces open-coded struct size calculations with struct_size() for devm_, f2fs_, and sock_* allocations.

Wei Chen	cc16d664e2	hwspinlock: add a CSR atlas7 driver Add hwspinlock support for the CSR atlas7 SoC. The Hardware Spinlock device on atlas7 provides hardware assistance for synchronization between the multiple processors in the system (dual Cortex-A7, CAN bus Cortex-M3 and audio DSP).
