Subject: mtd: onenand: omap2: Pass correct flags for prep_dma_memcpy
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8bcef0d54067077cf9a6cb129022c77559926e8c;p=linux.git

mtd: onenand: omap2: Pass correct flags for prep_dma_memcpy

The commit converting the driver to DMAengine was missing the flags for
the memcpy prepare call.
It went unnoticed since the omap-dma driver was ignoring them.

Fixes: 3ed6a4d1de2c5 (" mtd: onenand: omap2: Convert to use dmaengine for memcp")
