media: Add common header file with JPEG marker definitions
When compile-testing on mips/RB532 with W=1:
arch/mips/include/asm/mach-rc32434/rb.h:13: note: this is the location of the previous definition
13 | #define RST (1 << 15)
|
drivers/media/platform/mediatek/jpeg/mtk_jpeg_dec_parse.c:15: warning: "RST" redefined
15 | #define RST 0xd0
|
drivers/media/platform/renesas/rcar_jpu.c:77: warning: "RST" redefined
77 | #define RST 0xd0
|
"RST" is indeed a name too short to be conflict-free.
Fix this by creating a common <media/jpeg.h> header file, containing
definitions for all JPEG markers used, prefixed by "JPEG_MARKER_", based
on the existing private definitions in the Samsung S5P JPEG driver, and
convert all affected drivers.
