Thanks for the fix, looks good to me.

Sure. I think it should be: Fixes: 543be3d ("fpga: add device feature list support") Let me know if you want me to re-send the patch with that included. Cheers, -- David

Can you resend? Cheers

Because dfl.c uses the 'devm_ioremap', 'devm_iounmap', 'devm_ioremap_resource', and 'devm_platform_ioremap_resource' functions, it should depend on HAS_IOMEM. This fixes make allyesconfig under UML (ARCH=um), which doesn't provide HAS_IOMEM. Signed-off-by: David Gow <davidgow@google.com> --- drivers/fpga/Kconfig | 1 + 1 file changed, 1 insertion(+)
