From 0e8cf2be5c0a324809389c81e5555e8ccb6ba123 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 16 Mar 2022 18:53:50 +0200 Subject: [PATCH] staging: fbtft: Constify buf parameter in fbtft_dbg_hex() It's obvious that we don't and shouldn't modify buffer that is about to be dumped. Constify parameter in fbtft_dbg_hex() to make it clear.
