[v2,27/38] fbdev/sh7760fb: Alloc DMA memory from hardware device

Commit Message

Thomas Zimmermann June 12, 2023, 2:08 p.m. UTC

Pass the hardware device to the DMA helpers dma_alloc_coherent() and
dma_free_coherent(). The fbdev device that is currently being used is
a software device and does not provide DMA memory. Also update the
related dev_*() output statements similarly.
