If qcom_smem_get or qcom_smem_alloc return -EPROBE_DEFER, let the caller the caller handle it, instead of treating it as an error. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@xxxxxxx> --- v1: - TODO: Reading qcom_smsm_probe, I noticed memory leaks in error paths: smsm, smsm->entries, etc. are allocated (with devm_kzalloc), but not freed when the function returns early. This should be addressed at some point (in a separate patch). --- drivers/soc/qcom/smsm.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/soc/qcom/smsm.c b/drivers/soc/qcom/smsm.c index d0337b2a71c8..3918645e5708 100644 --- a/drivers/soc/qcom/smsm.c +++ b/drivers/soc/qcom/smsm.c @@ -439,7 +439,9 @@ static int smsm_get_size_info(struct qcom_smsm *smsm) } *info; info = qcom_smem_get(QCOM_SMEM_HOST_ANY, SMEM_SMSM_SIZE_INFO, &size); - if (PTR_ERR(info) == -ENOENT || size != sizeof(*info)) { + if (PTR_ERR(info) == -EPROBE_DEFER) { + return PTR_ERR(info); + } else if (PTR_ERR(info) == -ENOENT || size != sizeof(*info)) { dev_warn(smsm->dev, "no smsm size info, using defaults\n"); smsm->num_entries = SMSM_DEFAULT_NUM_ENTRIES; smsm->num_hosts = SMSM_DEFAULT_NUM_HOSTS; @@ -515,7 +517,9 @@ static int qcom_smsm_probe(struct platform_device *pdev) /* Acquire the main SMSM state vector */ ret = qcom_smem_alloc(QCOM_SMEM_HOST_ANY, SMEM_SMSM_SHARED_STATE, smsm->num_entries * sizeof(u32)); - if (ret < 0 && ret != -EEXIST) { + if (ret == -EPROBE_DEFER) { + return ret; + } else if (ret < 0 && ret != -EEXIST) { dev_err(&pdev->dev, "unable to allocate shared state entry\n"); return ret; } -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
