I have observed what appears to be a regression caused by this
patch when booting a kernel built using shmobile_defconfig on the koelsch
and lager boards.
I noticed this problem while testing next-20150129.
I have provided boot logs at the end of this email.

Thank you for the point. I should have tested using shmobile_defconfig.
So, I will submit a patch to fix this issue.
Detail:
- Since the defconfig doesn't enable CONFIG_GENERIC_PHY and CONFIG_PHY_RCAR_GEN2,
the driver's probe failed.
- Since we don't have dmac for usb at the moment if we use the defconfig,
dma_request_slave_channel_reason() will fail with ERR_PTR(-ENODEV).
- But, the current renesas_usbhs driver will keeps ERR_PTR(-ENODEV) in tx_chan and rx_chan.
So, if the driver calls usbhs_dma_quit, the driver calls dma_release_channel() with
wrong argument (ERR_PTR(-ENODEV)).
- So, I will write a patch to set tx_chan and rx_chan to NULL in the usbhsf_dma_init_dt()
if these values are IS_ERR.
Best regards,
Yoshihiro Shimoda
