Marcin Niestroj 362761299e power_supply: tps65217-charger: Fix NULL deref during property export ... This bug leads to: [ 1.906411] Unable to handle kernel NULL pointer dereference at virtual address 0000000c [ 1.914878] pgd = c0004000 [ 1.917786] [0000000c] *pgd=00000000 [ 1.921536] Internal error: Oops: 5 [#1] SMP ARM [ 1.926357] Modules linked in: [ 1.929556] CPU: 0 PID: 14 Comm: kworker/0:1 Not tainted 4.4.5 #18 [ 1.936006] Hardware name: Generic AM33XX (Flattened Device Tree) [ 1.942383] Workqueue: events power_supply_changed_work [ 1.947842] task: de2c41c0 ti: de2c8000 task.ti: de2c8000 [ 1.953483] PC is at tps65217_ac_get_property+0x14/0x28 [ 1.958937] LR is at tps65217_ac_get_property+0x10/0x28 Driver was trying to use drv_data in property get handler. However drv_data was not set, so it caused NULL pointer dereference. This patch properly sets drv_data during probe by power_supply_config parameter, so the property get handler works as desired.
