Subject: scripts/gdb: correct indentation in get_current_task
Date: Fri, 17 Feb 2023 19:11:53 -0600
Patch series "GDB: Support getting current task struct in UML", v2.
This patch (of 2):
There is an extra space in a couple blocks in get_current_task.
Though python does not care, let's make the spacing consistent.
Also, format better an if expression, removing unneeded parenthesis.
