Fatal error running coccicheck

[pamolloy]

It looks like coccicheck is failing for recent builds:

Run status=0; timeout 1d bash -c "source ./ci/build.sh ; check_coccicheck" || status=$?
  status=0; timeout 1d bash -c "source ./ci/build.sh ; check_coccicheck" || status=$?
  [ $status -eq 124 ] && echo "step_fail_coccicheck_timeout=true" >> "$GITHUB_ENV"
  exit $status

I tried to reproduce this on the main development branch by running the workflow manually, but the whole check task failed:

Run analogdevicesinc/doctools/checkout@action
Run # Resolve ref to pr number and merge commit sha
jq: error (at <stdin>:3): Cannot index array with string "status"
Error: Process completed with exit code 5.

with Enable debug, extensive logging is enabled for the shared actions

++ curl -s -H 'Authorization: ***' -H 'Accept: application/vnd.github+json' 'https://api.github.com/repos/analogdevicesinc/u-boot/pulls?head=analogdevicesinc:1b70d04794b2a62831769c1e0da0bfffa193f255&state=open'

++ jq -r '.status // empty'
++ echo '[

fixed at
analogdevicesinc/doctools@afa7809

but it seems it is from a workflow dispatch.
in workflow dispatch it searches for the pr of the commit, any, it found pr: 82 which is a single commit (1b70d04), merge_commit_sha was populated as 1b70d04 , which is not a merge commit but github told us it is.
https://api.github.com/repos/analogdevicesinc/u-boot/pulls/82

so an extra fix is needed that differentiate not enough depth from merge commit from normal commit:
analogdevicesinc/doctools@5ff2b91

now that the checkout corner case was fixed, how do you want to proceed in the cocci side?
