Subject: [PATCH 08/12] coresight: don't use bitmap_print_to_pagebuf()
Date: Thu, 19 Feb 2026 13:14:00 -0500 [thread overview]
Message-ID: <20260219181407.290201-9-ynorov@nvidia.com> (raw)
In-Reply-To: <20260219181407.290201-1-ynorov@nvidia.com>
Switch to a more common scnprintf("%*pbl") where appropriate.
