[ Upstream commit 2c231c0c1dec42192aca0f87f2dc68b8f0cbc7d2 ]
In ti_dra7_xbar_probe(), 'rsv_events' is allocated through kcalloc(). Then of_property_read_u32_array() is invoked to search for the property. However, if this process fails, 'rsv_events' is not deallocated, leading to a memory leak bug. To fix this issue, free 'rsv_events' before returning the error.
