[PATCH v4 09/11] powerpc/papr_scm: Return the string length from the sysfs show functions

[sashiko-bot at kernel.org]

> perf_stats_show() and flags_show() build their output with a seq_buf
> and return seq_buf_used(), which may include the trailing NUL byte
> when the seq_buf has overflowed. Use seq_buf_strlen() instead. As
> suggested in review, use it as well for flags_show()'s check whether
> any flag was printed.
> 
> Build tested ARCH=powerpc ppc64_defconfig with GCC powerpc64-linux-gnu
> 16.2.0:
> arch/powerpc/platforms/pseries/papr_scm.o
