backend: fix build against upcoming `gcc-14` (`-Werror=calloc-transposed-args`)
gcc-14
added a new -Wcalloc-transposed-args
warning recently. It
detected minor infelicity in calloc()
API usage in wlroots
:
../backend/libinput/tablet_pad.c: In function 'add_pad_group_from_libinput':
../backend/libinput/tablet_pad.c:36:38: error: 'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
36 | group->rings = calloc(sizeof(unsigned int), group->ring_count);
| ^~~~~~~~
../backend/libinput/tablet_pad.c:36:38: note: earlier argument should specify number of elements, later size of each element
