bcache: Fix incompatible pointer type warning
The function pointer release in struct block_device_operations should point to functions declared as void. Sparse warnings: drivers/md/bcache/super.c:656:27: warning: incorrect type in initializer (different base types) drivers/md/bcache/super.c:656:27: expected void ( *release )( ... ) drivers/md/bcache/super.c:656:27: got int ( static [toplevel] *<noident> )( ... ) drivers/md/bcache/super.c:656:2: warning: initialization from incompatible pointer type [enabled by default] drivers/md/bcache/super.c:656:2: warning: (near initialization for ‘bcache_ops.release’) [enabled by default] Signed-off-by: Emil Goode <emilgoode@gmail.com> Signed-off-by: Kent Overstreet <koverstreet@google.com>
