Re: [PATCH linux-next] fsi:(fsi-master-gpio)Convert sysfs sprintf/snprintf family to sysfs_emit

Hi,

Looks good, but we may as well do the other cases (in fsi-core) at the
same time.

There's a cocci script in the initial sysfs_emit series:

  https://lore.kernel.org/lkml/c22b7006813b1776467a72e716a5970e9277b4b7.camel@xxxxxxxxxxx/

Which gives me these additional changes:

Do you want to include these in your patch too?
