Subject: [PATCH] block, dax: use correct format string in bdev_dax_supported
The new message has an incorrect format string, causing a warning in some
configurations:
fs/block_dev.c: In function 'bdev_dax_supported':
fs/block_dev.c:779:5: error: format '%d' expects argument of type 'int', but argument 2 has type 'long int' [-Werror=format=]
"error: dax access failed (%d)", len);
This changes it to use the correct %ld instead of %d.
Fixes: 2093f2e9dfec ("block, dax: convert bdev_dax_supported() to dax_direct_access()")
