Subject: [PATCH 3/6] VT-d: bring print_qi_regs() in line with print_iommu_regs()
Date: Thu, 1 Apr 2021 10:44:55 +0200	[thread overview]
Message-ID: <c3401f8c-35b5-17d7-ae14-8c58e43b5cb9@suse.com> (raw)
In-Reply-To: <157e4a65-6d0b-7ea8-1c23-cd393c8c0d7f@suse.com>

Shorten the names printed. There's also no need to go through a local
variable.

While at it also constify the function's parameter.
