Subject: USB: serial: ti_usb_3410_5052: use strscpy() instead of strcpy()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=5a6a33b56402167ef019fd2520728e8c25614f74;p=thirdparty%2Fkernel%2Flinux.git

USB: serial: ti_usb_3410_5052: use strscpy() instead of strcpy()

Use a safer function strscpy() instead of strcpy() for copying to
arrays.

Only idiomatic code replacement, and no functional changes.
