Title
drm/msm: don't free the IRQ if it was not requested
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/msm: don't free the IRQ if it was not requested As msm_drm_uninit() is called from the msm_drm_init() error path, additional care should be necessary as not to call the free_irq() for the IRQ that was not requested before (because an error occured earlier than the request_irq() call). This fixed the issue reported with the following backtrace: [ 8.571329] Trying to free already-free IRQ 187 [ 8.571339] WARNING: CPU: 0 PID: 76 at kernel/irq/manage.c:1895 free_irq+0x1e0/0x35c [ 8.588746] Modules linked in: pmic_glink pdr_interface fastrpc qrtr_smd snd_soc_hdmi_codec msm fsa4480 gpu_sched drm_dp_aux_bus qrtr i2c_qcom_geni crct10dif_ce qcom_stats qcom_q6v5_pas drm_display_helper gpi qcom_pil_info drm_kms_helper qcom_q6v5 qcom_sysmon qcom_common qcom_glink_smem qcom_rng mdt_loader qmi_helpers phy_qcom_qmp ufs_qcom typec qnoc_sm8350 socinfo rmtfs_mem fuse drm ipv6 [ 8.624154] CPU: 0 PID: 76 Comm: kworker/u16:2 Not tainted 5.18.0-rc5-next-20220506-00033-g6cee8cab6089-dirty #419 [ 8.624161] Hardware name: Qualcomm Technologies, Inc.
