[PATCH v2 1/2] power: supply: Fix tps65217-charger vs vbus irq conflict
Posted by Grant B Adams 2 years, 3 months ago
Enabling the tps65217-charger driver/module causes an interrupt conflict
with the vbus driver resulting in a probe failure.
The conflict is resolved by changing both driver's threaded interrupt
request function from IRQF_ONESHOT to IRQF_SHARED.

Your commit message does not explain why IRQF_ONESHOT is dropped;
IRQF_ONESHOT and IRQF_SHARED are not mutually exclusive.
