The use of 'goto' is not needed here IMHO. I think:
if (geni_status & M_GENI_CMD_ACTIVE) {
do_the_stuff
}
pm_runtime_put_sync_suspend(...);
is more readable, in fact. Also, I don't think we really need the 'cur'
variable and just use 'gi2c->cur' but that's very minor and you can keep
it if you like it.
Reset looks good!
