[PATCH v2 2/7] mn10300: Provide dummy dma_alloc_attrs() and dma_free_attrs()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



allmodconfig fails to build with following errors.

drivers/media/platform/sti/bdisp/bdisp-hw.c:
	In function 'bdisp_hw_free_nodes':
drivers/media/platform/sti/bdisp/bdisp-hw.c:132:3: error:
	implicit declaration of function 'dma_free_attrs'

drivers/media/platform/sti/bdisp/bdisp-hw.c:
	In function 'bdisp_hw_alloc_nodes':
drivers/media/platform/sti/bdisp/bdisp-hw.c:157:2: error:
	implicit declaration of function 'dma_alloc_attrs'

mn10300 does not provide those functions at this time.
Provide dummy implementations to avoid build errors.
