When compiling with gcc 13 with -Warray-bounds enabled:
In file included from drivers/iio/proximity/irsd200.c:15:
In function ‘iio_push_to_buffers_with_timestamp’,
inlined from ‘irsd200_trigger_handler’ at drivers/iio/proximity/irsd200.c:770:2:
./include/linux/iio/buffer.h:42:46: error: array subscript ‘int64_t {aka long long int}[0]’
is partly outside array bounds of ‘s16[1]’ {aka ‘short int[1]’} [-Werror=array-bounds=]
42 | ((int64_t *)data)[ts_offset] = timestamp;
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~
drivers/iio/proximity/irsd200.c: In function ‘irsd200_trigger_handler’:
drivers/iio/proximity/irsd200.c:763:13: note: object ‘buf’ of size 2
763 | s16 buf = 0;
| ^~~
The problem seems to be that irsd200_trigger_handler() is taking a s16
variable as an int64_t buffer. As Jonathan suggested [1], fix it by
extending the buffer to a two-element array of s64.
