Subject: [PATCH 02/12] octeontx2-af: siplify rvu_debugfs
Date: Thu, 19 Feb 2026 13:13:54 -0500	[thread overview]
Message-ID: <20260219181407.290201-3-ynorov@nvidia.com> (raw)
In-Reply-To: <20260219181407.290201-1-ynorov@nvidia.com>

The driver uses bitmap_print_to_pagebuf() to store human-readable
bitmaps representations in a temporary buffers; and then feed
seq_printf() with it.

Switch to using seq_printf("%*pb") directly and drop intermediate
buffer.
