[PATCH v2 03/15] media: s5p-mfc: Replace mem_dev_* entries with an array

[Marek Szyprowski <m.szyprowski@samsung.com>]

Internal MFC driver device structure contains two pointers to devices used
for DMA memory allocation: mem_dev_l and mem_dev_r. Replace them with the
mem_dev[] array and use defines for accessing particular banks. This will
help to simplify code in the next patches.
