Subject[PATCH -next] MIPS: OCTEON: octeon-usb: Use devm_platform_get_and_ioremap_resource()
Date
Remove unneeded error handling on the result of a call
to platform_get_resource() when the value is passed to
devm_ioremap_resource().

And use devm_platform_get_and_ioremap_resource() to simplify
code.
