From: Colin Ian King <colin.k...@canonical.com>
The for-loop iterates with a u8 loop counter i and compares this
with the loop upper limit of pm8001_ha->max_q_num which is a u32
type. There is a potential infinite loop if pm8001_ha->max_q_num
is larger than the u8 loop counter. Fix this by making the loop
counter the same type as pm8001_ha->max_q_num.
Addresses-Coverity: ("Infinite loop")
