Description
In the Linux kernel, the following vulnerability has been resolved: drm/bridge: samsung-dsim: Fix memory leak in error path In samsung_dsim_host_attach(), drm_bridge_add() is called to add the bridge. However, if samsung_dsim_register_te_irq() or pdata->host_ops->attach() fails afterwards, the function returns without removing the bridge, causing a memory leak. Fix this by adding proper error handling with goto labels to ensure drm_bridge_remove() is called in all error paths. Also ensure that samsung_dsim_unregister_te_irq() is called if the attach operation fails after the TE IRQ has been registered. samsung_dsim_unregister_te_irq() function is moved without changes to be before samsung_dsim_host_attach() to avoid forward declaration.
