MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On architectures where an s64 is only 32-bit aligned insufficient padding would be left between the earlier elements and the timestamp. Use aligned_s64 to enforce the correct placement and ensure the storage is large enough. Fixes: 54e018da3141 ("iio:ad7266: Mark transfer buffer as __be16") # aligned_s64 is much newer.
