Greg, building for corgi with gcc7 I notice this single warning: /drivers/dma/pxa_dma.c:1324:34: warning: duplicate 'const' declaration specifier [-Wduplicate-decl-specifier] static const struct of_device_id const pxad_dt_ids[] ... There was a wrong backport of one patch and pxa_dma was fixed by 4.4.90. Unfortunately the patch "4e0def8 dmaengine: pxa_dma: remove duplicate const qualifier" was forgotten. Thanks Andrea
