[Scst-devel] [PATCH 1/5] scst: fix garbage in trace_level files

[Tony B. <to...@cy...>]

'hd /sys/kernel/scst_tgt/trace_level' shows a series of extraneous nul
chars at the end of the first line.

Fixes: 9cbca538303f ("scst: Replace sprintf() with scnprintf() in sysfs callbacks")
Signed-off-by: Tony Battersby <to...@cy...>
