With this series applied, I see the following in my sh4 boot tests.
sb 1-1: new full-speed USB device number 2 using sm501-usb
sm501-usb sm501-usb: OHCI Unrecoverable Error, disabled
sm501-usb sm501-usb: HC died; cleaning up
This is a persistent problem. Reverting upstream commit 2f606da7823
("mfd: sm501: Set coherent_dma_mask when creating subdevices") does not
make a difference.
The problem is gone if I do not apply 'driver core: initialize a default
DMA mask for platform device'.
On the plus side, the sparc warnings are gone.
