[PATCH 12/15] media: s5k5baf: avoid gcc-10 zero-length-bounds warning

[Arnd Bergmann]

gcc-10 warns about accessing a zero-length struct member:

drivers/media/i2c/s5k5baf.c: In function 's5k5baf_load_setfile':
drivers/media/i2c/s5k5baf.c:390:13: warning: array subscript 65535 is outside the bounds of an interior zero-length array 'struct <anonymous>[0]' [-Wzero-length-bounds]
  390 |   if (f->seq[i].offset + d <= end)
      |       ~~~~~~^~~

This should really be a flexible-array member, but the structure
already has one. I experimentally confirmed that swapping the two
avoids the warning, as the 'data[]' array is not accessed like this.

Fixes: 3ba225b506a2 ("treewide: Replace zero-length array with flexible-array member")
Fixes: 7d459937dc09 ("[media] Add driver for Samsung S5K5BAF camera sensor")
