If CONFIG_IO_URING is not set:
include/linux/io_uring.h:65:12: error: ‘io_uring_cmd_import_fixed’ defined but not used [-Werror=unused-function]
65 | static int io_uring_cmd_import_fixed(u64 ubuf, unsigned long len, int rw,
| ^~~~~~~~~~~~~~~~~~~~~~~~~
Fix this by adding the missing "inline" keyword.
Fixes: a9216fac3e ("io_uring: add io_uring_cmd_import_fixed")
