Subject: [AUTOSEL,4.14,38/69] USB: omap_udc: fix rejection of out transfers when DMA is used
Date: Wed, 5 Dec 2018 04:42:16 -0500 [thread overview]
Message-ID: <20181205094247.6556-38-sashal@kernel.org> (raw)
From: Aaro Koskinen <aaro.koskinen@iki.fi>
[ Upstream commit 069caf5950dfa75d0526cd89c439ff9d9d3136d8 ]
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.
Fixes: 387f869d2579 ("usb: gadget: u_ether: conditionally align transfer size")
