This was partly done using the semantic patch scripts/coccinelle/api/devm_ioremap_resource.cocci The error-handling code on the call to platform_get_resource was removed manually, and the initialization of smmu->size was manually moved lower, to take advantage of the NULL test on res performed by devm_ioremap_resource.
