From 2681795b5e7a5bf336537661010072f4c22cea31 Mon Sep 17 00:00:00 2001 From: Nikolaus Voss Date: Fri, 28 Jun 2019 11:01:09 +0200 Subject: [PATCH] drivers/usb/typec/tps6598x.c: fix 4CC cmd write 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.
