module: fix building with sysfs disabled
Sysfs support might be disabled so we need to guard the code that instantiates "compression" attribute with an #ifdef. Fixes: b1ae6dc41eaa ("module: add in-kernel support for decompressing") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
