Just use masked vmf->address which already has the appropriate type.

However, the recent addition of IOMMU support did not account for this requirement. Therefore host1x engines cannot be used if IOMMU is enabled. This patch implements kmap, kunmap, mmap and munmap functions to host1x buffer objects.

The only function that calls tegra_clk_sor_brick_register() is the probe function and it correctly checks and handles the return value, which, on failure, will cause devm_ allocated memory to be freed automatically.

So checking for NULL here is pointless and can never trigger. Check the returned value with IS_ERR instead and propagate this value as done in the other functions which call devm_pinctrl_register().
