Hi,

Thank you for your patch Thomas; I think it works :)

With your patch, next-20130702 boots pretty far on i.MX6 sabre sd, until it crashes in wm8962_probe(). Without this patch, I don't even get the first kernel messages. (Both with ARM config imx_v6_v7_defconfig.)

Also, I am pretty sure the wm8962_probe() issue is unrelated, as it happened even before this timer thing.

Thank you!

Best regards,

V.
