in this function you conditionally call pwrseq_power_on()
but on error you unconditionally call pwrseq_power_off()

in the below function you conditionally call pwrseq_power_off()

so there is inconsistency.

note that both pwrseq_power_on() and pwrseq_power_off() handle a NULL
pwrseq_desc so is there any reason to not just call both both functions
unconditionally everywhere?
