This issue was detected by using the Coccinelle software.
Move the jump label directly before the desired log statement so that the variable "err" will not be checked once more after it was determined that a call of the function "__mmc_set_signal_voltage" or "__mmc_switch" failed. Use the identifier "report_failure" instead of the label "err".
