Subject: drm/msm/dpu: pass irq to dpu_encoder_helper_wait_for_irq()
Git-commit: 1e7ac595fa46eab834535dca1f38e0784b3594ad
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Pass IRQ number directly rather than passing an index in the dpu_encoder's irq table.
