Subject: [PATCH] iio: accel: adxl355: Make timestamp 64-bit aligned using
aligned_s64
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The IIO ABI requires 64-bit aligned timestamps. In this case insufficient
padding would have been added on architectures where an s64 is only 32-bit
aligned. Use aligned_s64 to enforce the correct alignment.
