Hi,
I had this queued up for v3.20, however, when rebasing on top
of v3.19-rca (previous base was v3.18) I noticed that this patch
appears to cause booting koelsch with shmobile_defconfig to
stop at:
rcar_sound ec500000.rcar_sound: can't get dma channel
rcar_sound ec500000.rcar_sound: src[3] (Gen2) failed
rcar_sound ec500000.rcar_sound: ssi[1] fallback to PIO mode
rcar_sound ec500000.rcar_sound: probed
TCP: cubic registered
NET: Registered protocol family 10
da9063 6-0058: Failed to read IRQ status: -6
sit: IPv6 over IPv4 tunneling driver
NET: Registered protocol family 17
Key type dns_resolver registered
random: nonblocking pool is initialized
I have (hopefully temporarily) dropped this patch accordingly.
