Subject: usb: host: ehci-dbg: use scnprintf() in qh_lines()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5355977947dc4da93ac05a72989fecc95bc6dca;p=linux-beck.git

usb: host: ehci-dbg: use scnprintf() in qh_lines()

This patch replaces two snprintf() calls with scnprintf() in qh_lines()
and hence removes the unneeded sequential truncation tests.
