The statically allocated 'struct qcom_icc_desc' is not modified by the driver and like all other instances should be const. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250109164630.175093-1-krzysztof.kozlowski@linaro.org Signed-off-by: Georgi Djakov

interconnect: qcom: icc-rpm: Set the count member before accessing the flex array

2024-12-17T12:03:02Z

The following UBSAN error is reported during boot on the db410c board on a clang-19 build: Internal error: UBSAN: array index out of bounds: 00000000f2005512 [#1] PREEMPT SMP ... pc : qnoc_probe+0x5f8/0x5fc ... The cause of the error is that the counter member was not set before accessing the annotated flexible array member, but after that. Fix this by initializing it earlier.
