Subject: [PATCH] media: platform: samsung: s5p-jpeg: Remove deadcode

From: "Dr. David Alan Gilbert" <linux@...blig.org>

exynos3250_jpeg_operating() has been unused since it was added in 2014's
commit 3246fdaa0ac2 ("[media] s5p-jpeg: Add support for Exynos3250 SoC")

exynos4_jpeg_get_fifo_status(), exynos4_jpeg_get_frame_size(), and
exynos4_jpeg_set_timer_count() have been unused since they were added by
commit 80529ae5c137 ("[media] s5p-jpeg:  JPEG codec")

Remove them.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
