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. Signed-off-by: Srivatsa S.
