Hi All:
drivers/regulator/ltc3589.c
Variable "irqstat" in function ltc3589_isr() could be uninitialized if regmap_read() returns -EINVAL. But it's directly used later without the return check, which is potentially unsafe.
Also, we cannot simply return -EINVAL in ltc3589_isr() because the error code is out of the return type: irqreturn_t.
Thanks for your time to check this case.
