Looks good. Thanks. The same error is present elsewhere in the patch and other patches too.

Same with USB Not sure what you mean by "next section"? goto based error recovery is more commonly used and probably more preferred as it is easier to extend. You can look at function da850_evm_ui_expander_setup() of arch/arm/mach-davinci/board-da850-evm.c for an example.
