## Description

In the Linux kernel, the following vulnerability has been resolved:  drm/bridge: synopsys: dw-dp: fix error paths of dw_dp_bind  Fix several issues in dw_dp_bind() error handling:  1. Missing return after drm_bridge_attach() failure - the function    continued execution instead of returning an error.  2. Resource leak: drm_dp_aux_register() is not a devm function, so    drm_dp_aux_unregister() must be called on all error paths after    aux registration succeeds. This affects errors from:    - drm_bridge_attach()    - phy_init()    - devm_add_action_or_reset()    - platform_get_irq()    - devm_request_threaded_irq()  3. Bug fix: platform_get_irq() returns the IRQ number or a negative    error code, but the error path was returning ERR_PTR(ret) instead    of ERR_PTR(dp->irq).  Use a goto label for cleanup to ensure consistent error handling.
