Both the tps65217-charger and vbus drivers are trying to allocate the same TPS65217 device interrupt line (TPS65217 is a TI power management IC) which results in the following error and a probe failure: genirq: Flags mismatch irq 148. 00002000 (vbus) vs. 00000000 (tps65217-charger) For the Beaglebone Black's config the tps65217-charger driver is currently disabled and therefore no conflict. Based on comments from Robert C Nelson this driver has been disabled for a long time and he is uncertain on the reasons why it was disabled. With a battery connected to the BBB, I re-enabled the tps65217-charger driver which resulted in the abovementioned. The conflict is resolved by changing both driver's threaded interrupt request function from IRQF_ONESHOT to IRQF_SHARED. Changes in v2: Initial patches where emailed individually and not threaded. V2 patches sent as email thread.
