Re: qmi_wwan: Null pointer dereference when removing driver

Yup, that patch works perfectly, and yes the device is a multi-tty device. Cheers for everything! On 08/08/17 18:35, Bjørn Mork wrote: Nathaniel Roach writes: Unsure at which point was added, but issue not present in stock debian 4.11 kernel. Running on a Thinkpad

Re: qmi_wwan: Null pointer dereference when removing driver

I probably should have put the model in the original report, but it's a E371. I'll put it back in the machine and test it when I'm back home. Thanks for the work! On 08/08/17 18:35, Bjørn Mork wrote: Nathaniel Roach writes: Unsure at which point was added, but issue

qmi_wwan: Null pointer dereference when removing driver

Unsure at which point was added, but issue not present in stock debian 4.11 kernel. Running on a Thinkpad X220 with coreboot. I'm building from upstream. When I attempt to remove the qmi_wwan module (which also happens pre-suspend) the rmmod process gets killed, and the following shows in
