From: Nikolaus Voss <nikolaus.voss@xxxxxxxxxxxxxxxxxxxxx> commit 2681795b5e7a5bf336537661010072f4c22cea31 upstream. Writing 4CC commands with tps6598x_write_4cc() already has a pointer arg, don't reference it when using as arg to tps6598x_block_write(). Correcting this enforces the constness of the pointer to propagate to tps6598x_block_write(), so add the const qualifier there to avoid the warning.
