[PATCH] devtools: honor -n flag regardless of stdin state

[PATCH] devtools: honor -n flag regardless of stdin state

[Ali Alnubani]

The checkpatches.sh script was checking if stdin is a terminal before
honoring the -n flag, causing it to incorrectly attempt to read patches
from stdin when run without a TTY (e.g., in Jenkins/CI pipelines).

Reorder the conditionals to check for the -n flag before checking stdin
state. This ensures the -n flag takes precedence and the script checks
git commits as intended.
