5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Zhipeng Lu <alexious@xxxxxxxxxx> [ Upstream commit 809aa64ebff51eb170ee31a95f83b2d21efa32e2 ] When dma_alloc_coherent fails to allocate dd->cr_base[i].va, init_credit_return should deallocate dd->cr_base and dd->cr_base[i] that allocated before. Or those resources would be never freed and a memleak is triggered.
