#     media: s5k5baf: avoid gcc-10 zero-length-bounds warning
#     
#     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")
