However, if samsung_dsim_register_te_irq() or\npdata->host_ops->attach() fails afterwards, the function returns\nwithout removing the bridge, causing a memory leak.\n\nFix this by adding proper error handling with goto labels to ensure\ndrm_bridge_remove() is called in all error paths. Also ensure that\nsamsung_dsim_unregister_te_irq() is called if the attach operation\nfails after the TE IRQ has been registered.\n\nsamsung_dsim_unregister_te_irq() function is moved without changes\nto be before samsung_dsim_host_attach() to avoid forward declaration."
