[PATCH] w1: therm: Use str_yes_no helper in w1_slave_show
Posted by Thorsten Blum 3 months ago
Replace hard-coded strings with the str_yes_no() helper function. This
unifies the output and helps the linker with deduplication, which can
result in a smaller binary.

That's sysfs interface, right? So an ABI and you change here caps, which
might matter or might not, but anyway some sort of analysis of that
should be in the commit msg. Otherwise better not to touch ABI.

Best regards,

Yeah, I guess it's better not to change it then.

Thanks,
