Also remove MODULE_NAME and a BUG_ON check, both unneeded.
This fixes a warning about string truncation in snprintf that
will never happen in practice:
drivers/md/dm-vdo/vdo.c: In function ‘vdo_make’:
drivers/md/dm-vdo/vdo.c:564:5: error: ‘%s’ directive output may be truncated writing up to 55 bytes into a region of size 16 [-Werror=format-truncation=]
"%s%u", MODULE_NAME, instance);
^~
drivers/md/dm-vdo/vdo.c:563:2: note: ‘snprintf’ output between 2 and 66 bytes into a destination of size 16
snprintf(vdo->thread_name_prefix, sizeof(vdo->thread_name_prefix),
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
"%s%u", MODULE_NAME, instance);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
