Like said above,
[    5.965191] kobject_add_internal failed for qfprom0 with -EEXIST,
don't try to register things with the same name in the same directory.
[    5.969110] qcom,qfprom: probe of 5c000.qfprom failed with error -17

Following kernel crash noticed on arm64 Qcom dragonboard 410c
device.

We will bisect this problem and get back to you soon.
