From d8a5b59c5fc75c99ba17e3eb1a8f580d8d172b28 Mon Sep 17 00:00:00 2001 From: Johan Hovold johan+linaro@kernel.org Date: Mon, 14 Nov 2022 09:13:41 +0100 Subject: [PATCH] phy: qcom-qmp-combo: fix out-of-bounds clock access
The SM8250 only uses three clocks but the DP configuration erroneously described four clocks.
In case the DP part of the PHY is initialised before the USB part, this would lead to uninitialised memory beyond the bulk-clocks array to be treated as a clock pointer as the clocks are requested based on the USB configuration.
