[PATCH 6.1 0774/1146] power: supply: z2_battery: Fix possible memleak in z2_batt_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit 955bee204f3dd307642c101b75e370662987e735 ]

If devm_gpiod_get_optional() returns error, the charger should be
freed before z2_batt_probe returns according to the context. We
fix it by just gotoing to 'err' branch.
