11e1cc09bc fbdev: sh7760fb: Fix a possible memory leak in sh7760fb_alloc_mem() 
[ Upstream commit f89d17ae2ac42931be2a0153fecbf8533280c927 ]

When information such as info->screen_base is not ready, calling
sh7760fb_free_mem() does not release memory correctly. Call
dma_free_coherent() instead.

c3cf380435 fbdev/sh7760fb: Alloc DMA memory from hardware device 
[ Upstream commit 8404e56f4bc1d1a65bfc98450ba3dae5e653dda1 ]

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.
