Subject: [media] s5p-jpeg: Split jpeg-hw.h to jpeg-hw-s5p.c and jpeg-hw-s5p.c
X-Git-Tag: firefly_0821_release~176^2~3573^2~987
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9f7b62d9f961e0a839de7dc5547db0f5a612cfd4;p=firefly-linux-kernel-4.4.55.git
[media] s5p-jpeg: Split jpeg-hw.h to jpeg-hw-s5p.c and jpeg-hw-s5p.c
Move function definitions from jpeg-hw.h to jpeg-hw-s5p.c,
add "s5p" prefix and put function declarations in the jpeg-hw-s5p.h.
