Currently there are some issues with the ucc_of_parse_tdm function: 1, a possible null pointer dereference in ucc_of_parse_tdm, detected by the semantic patch deref_null.cocci, with the following warning: drivers/soc/fsl/qe/qe_tdm.c:177:21-24: ERROR: pdev is NULL but dereferenced. 2, dev gets modified, so in any case that devm_iounmap() will fail even when the new pdev is valid, because the iomap was done with a different pdev. 3, there is no driver bind with the "fsl,t1040-qe-si" or "fsl,t1040-qe-siram" device. So allocating resources using devm_*() with these devices won't provide a cleanup path for these resources when the caller fails. This patch fixes them.
