Subject: [PATCH] selinux: avoid printk_ratelimit()
Date: Fri,  5 Apr 2024 17:15:23 +0200	[thread overview]
Message-ID: <20240405151523.92010-1-cgoettsche@seltendoof.de> (raw)

From: Christian Göttsche <cgzones@googlemail.com>

The usage of printk_ratelimit() is discouraged, see
include/linux/printk.h, thus use pr_warn_ratelimited().

While editing this line address the following checkpatch warning:

    WARNING: Integer promotion: Using 'h' in '%hu' is unnecessary
