Subject: EDAC: Don't give write permission to read-only files
I get the following warning on boot:
------------[ cut here ]------------
WARNING: at drivers/base/core.c:575 device_create_file+0x9a/0xa0()
Hardware name: -[8737R2A]-
Write permission without 'store'
...
</snip>
Drilling down, this is related to dynamic channel ce_count attribute
files sporting a S_IWUSR mode without a ->store() function. Looking
around, it appears that they aren't supposed to have a ->store()
function. So remove the bogus write permission to get rid of the
warning.
