[PATCH RESEND] fpga: bridge: Use str_enabled_disabled helper in state_show
Posted by Thorsten Blum 1 month, 1 week ago
Replace hard-coded strings with the str_enabled_disabled() helper. This
unifies the output and helps the linker with deduplication, which can
result in a smaller binary.

Would you consider including this patch[1] to this?

Oh... This str_enabled_disabled() is exactly the same trivial changes I
was thinking of when I wrote that comment.

But hi Dinh, took another look, the state_show() in the same file is
already switched to sysfs_emit() by previous valid change. So to keep the
file consistency, it's good to change to sysfs_emit() for name_show().
Sorry for my neglection.
