The driver is using -1 instead of the -ENOMEM defined macro to specify that a buffer allocation failed. Using the correct error code is more intuitive
Smatch tool warning: drivers/mtd/inftlmount.c:333 check_free_sectors() warn: returning -1 instead of -ENOMEM is sloppy drivers/mtd/nftlmount.c:272 check_free_sectors() warn: returning -1 instead of -ENOMEM is sloppy
No functional change, just more standardized.
