Subject: [PATCH v2 5/5] USB: omap_udc: fix rejection of out transfers when DMA is used
Date:   Sun, 25 Nov 2018 00:17:08 +0200

Commit 387f869d2579 ("usb: gadget: u_ether: conditionally align
transfer size") started aligning transfer size only if requested,
breaking omap_udc DMA mode. Set quirk_ep_out_aligned_size to restore
the old behaviour.
