Subjectconcerns about sysfs_ops
From
Date
Dear Mochel,
I found you removed off/count params in new sysfs_ops functions. That's
good change for show functions, but for store function, if you don't
give the len of data, the chained xxx_store function has to assume
or/and guess how long the data is. This might be a potential issue. So I
suggest you add 'size_t count' in store function of sysfs_ops.

size_t count);
};
