[ Upstream commit 3268a4d9b0b85a4382e93bdf7be5400a73db74c5 ]
The tmp is defined as u32 type, which results in invalid processing of tmp<0 in function rk817_read_or_set_full_charge_on_boot(). Therefore, drop the comparison.
drivers/power/supply/rk817_charger.c:828 rk817_read_or_set_full_charge_on_boot() warn: unsigned 'tmp' is never less than zero. drivers/power/supply/rk817_charger.c:788 rk817_read_or_set_full_charge_on_boot() warn: unsigned 'tmp' is never less than zero.
