ec/google/wilco/mailbox: Fix format warning by using size_t length modifier
Building google/sarien with a 64-bit compiler (x86_64-linux-gnu) fails
with the error below.
src/ec/google/wilco/mailbox.c: In function 'wilco_ec_transfer':
src/ec/google/wilco/mailbox.c:184:43: error: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]
184 | printk(BIOS_ERR, "%s: data too short (%lu bytes, expected %zu)",
| ~~^
| |
| long unsigned int
| %u
185 | __func__, rs.data_size - skip_size, msg->response_size);
| ~~~~~~~~~~~~~~~~~~~~~~~~
| |
| size_t {aka unsigned int}
`data_size` has type `uint16_t`, and `skip_size` has type `size_t`,
whose size differs in 32-bit (unsigned int) and 64-bit (unsigned long).
So use the length modifier `z` for a `size_t` argument.
