Subject: [PATCH] crypto: cavium: fix dma_free_coherent() size
Date: Thu, 18 Dec 2025 10:56:45 +0100 [thread overview]
Message-ID: <20251218095647.45214-2-fourier.thomas@gmail.com> (raw)
The size of the buffer in alloc_command_queues() is
curr->size + CPT_NEXT_CHUNK_PTR_SIZE, so used that length for
dma_free_coherent().
Fixes: c694b233295b ("crypto: cavium - Add the Virtual Function driver for CPT")
