Subject: [PATCH] powerpc/xmon: fix task state output
Git-commit: b1f896ce3542eb2eede5949ee2e481526fae1108
Patch-mainline: v5.16-rc1
References: stable-5.14.19
[ Upstream commit b1f896ce3542eb2eede5949ee2e481526fae1108 ]
p_state is unsigned since the commit 2f064a59a11f
The patch also uses TASK_RUNNING instead of null.
