Remove the function mmio_size_show() that is not used anywhere.

This was partially found by using a static code analysis program called cppcheck.

Did you compile check this patch?

  drivers/misc/cxl/sysfs.c:291:74: error: ‘mmio_size_show’ undeclared here (not in a function)

It's used here:
        static struct device_attribute afu_attrs[] = {
        	__ATTR_RO(mmio_size),

Thanks for letting me know which tool to avoid :-)

Hi

Sorry about that.

Strange because I compile everything as allyesconfig, allmodconfig and
allnoconfig.

Kind regards

The allyes should have picked it up, so you must have done something wrong.

Please be more careful with these attribute routines, they are not visible with
grep.
