Subject: [PATCH] printk: make suppress_panic_printk static

References: SLE Realtime Extension
Patch-mainline: v5.18-rc1
Git-commit: ce06e863f36f16cdc3b84c7206cd13d5f597d623

This symbol is not used outside of printk.c, so marks it static.

Fix the following sparse warning:

kernel/printk/printk.c:100:19: warning: symbol 'suppress_panic_printk'
was not declared. Should it be static?
