However, IPQ9574 SoC implements CPRv4 without ACC. This causes NULL pointer accesses resulting in crashes. Hence, check if 'acc_desc' is populated before using it. Signed-off-by: Varadarajan Narayanan --- v6: Changes done in the previous version of this patch got squashed into Konrad's V15 - https://lore.kernel.org/lkml/20240708-topic-cpr3h-v15-9-5bc8b8936489@linaro.org/ In v14, cpr_set_acc() was invoked from cpr_pre_voltage() or cpr_post_voltage(). Both of those functions invoked cpr_set_acc() only if drv->tcsr was not NULL (and that implied acc_desc != NULL). In v15, cpr_pre_voltage() & cpr_post_voltage() have been removed and cpr_set_acc() is called even though acc_desc is NULL resulting in NULL pointer access. Hence allow cpr_set_acc() to proceed only if acc_desc is set. v5: Add acc_desc check in a different way without breaking other SoC v4: Undo the acc_desc validation in probe function as that could affect other SoC. --- drivers/pmdomain/qcom/cpr3.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/drivers/pmdomain/qcom/cpr3.c b/drivers/pmdomain/qcom/cpr3.c index de24973978b7..d594bc79be1c 100644 --- a/drivers/pmdomain/qcom/cpr3.c +++ b/drivers/pmdomain/qcom/cpr3.c @@ -536,12 +536,15 @@ static void cpr_corner_restore(struct cpr_thread *thread, static void cpr_set_acc(struct cpr_drv *drv, int f) { const struct acc_desc *desc = drv->acc_desc;
