From: Ben Greear <greearb at candelatech.com>
This first release is all about checking for ath10k firmware
crashes. Could be extended later for other modules/bugs/etc.

v2: Add comments about this being for ath10k firmware
Change name to 'ct-bugcheck' since this is mostly about
ct ath10k firmware at this point.
