In macro QSEECOM_ALIGN, change (x + QSEECOM_ALIGN_SIZE) to (x + QSEECOM_ALIGN_MASK); otherwise, when x is already aligned, QSEECOM_ALIGN(x) will get (x + QSEECOM_ALIGN_SIZE), but it should be x. Also, remove the dulplicate QSEECOM_ALIGN definition in hdcp.c and mpq_sdmx.c, since they already include "qseecom_kernel.h" Change-Id: I9dbcadb618372fce71c2ff7ab62ca691afe7c7fa Signed-off-by: Zhen Kong <zkong@codeaurora.org>
