I think those are based on the error handling in
da850_evm_ui_expander_setup() which means that the 'exp' in
'exp_setup_' stands-for IO-expander.

Based on the function names where the your exp_setup_* labels were
introduced I think that the label could be renamed 'mmc_setup_*' and
'usb11_setup_*'.
