In init_nand_dma there was code to detect failure to allocate memory but it had two problems. Firstly the 2nd clause when info->tx_desc was NULL attempted to free info->tx_desc when it should be freeing info->rx_desc. Secondly there was no detection of both allocations failing, arguably the more likely scenario. Refactor the code to simplify it and just fail as soon as either allocation fails.
