Arnd BergmannandGreg Kroah-Hartman 30a4e81edb media: st-delta: avoid excessive stack usage ...

[ Upstream commit 5954ad7d1a ]

Building with a reduced stack warning limit shows that delta_mjpeg_decode()
copies a giant structure to the stack each time but only uses three of
its members:

drivers/media/platform/st/sti/delta/delta-mjpeg-dec.c: In function 'delta_mjpeg_decode':
drivers/media/platform/st/sti/delta/delta-mjpeg-dec.c:427:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Open-code the passing of the structure members that are actually used here.
