If anyone has any objections, please let me know. ------------------ From: Alok Tiwari [ Upstream commit 7727ec1523d7973defa1dff8f9c0aad288d04008 ] Add missing post-increment operators for byte pointers in the loop that copies remaining bytes in xemaclite_aligned_read(). Without the increment, the same byte was written repeatedly to the destination.
