[ Upstream commit 040f31196e8b2609613f399793b9225271b79471 ]
When building with W=1, gcc points out that the __packed attribute on struct qm_eqcr_entry conflicts with the 8-byte alignment attribute on struct qm_fd inside it:
drivers/soc/fsl/qbman/qman.c:189:1: error: alignment 1 of 'struct qm_eqcr_entry' is less than 8 [-Werror=packed-not-aligned]
I assume that the alignment attribute is the correct one, and that qm_eqcr_entry cannot actually be unaligned in memory, so add the same alignment on the outer struct.
