Subject: [PATCH 06/22] fbdev: da8xx: Don't use GFP_DMA when calling dma_alloc_coherent()

From: Baoquan He <[email-masked]>
Date: Sat, 19 Feb 2022 08:52:05 +0800

dma_alloc_coherent() allocates dma buffer with device's addressing
limitation in mind. It's redundent to specify GFP_DMA when calling
dma_alloc_coherent().
