-Subject: [PATCH 2/2] usb: dwc2: Fix inefficient copy of unaligned buffers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Make sure only to copy any actual data rather than the whole buffer,
-when releasing the temporary buffer used for unaligned non-isochronous
-transfers.
-
-Taken directly from commit 0efd937e27d5e ("USB: ehci-tegra: fix inefficient
-copy of unaligned buffers")
-
-Tested with Lantiq xRX200 (MIPS) and RPi Model B Rev 2 (ARM)
-
