[ Upstream commit ccf193dee1f0fff55b556928591f7818bac1b3b1 ]
clang static analysis flags this error
88pm860x_battery.c:522:19: warning: Assigned value is garbage or undefined [core.uninitialized.Assign] info->start_soc = soc; ^ ~~~ soc is set by calling calc_soc. But calc_soc can return without setting soc.
So check the return status and bail similarly to other checks in pm860x_init_battery and initialize soc to silence the warning.
Fixes: a830d28b48bf ("power_supply: Enable battery-charger for 88pm860x")
