+Subject: [PATCH 0768/2940] drm/amd/display: Fix misleading buffer information
+
+RETIMER_REDRIVER_INFO shows the buffer as a decimal value with a '0x'
+prefix, which is somewhat misleading.
+
+Fix it to print hexadecimal, as was intended.
+
+Fixes: 2f14bc89("drm/amd/display: add retimer log for HWQ tuning use.")
