Subject: ALSA: spi: Use safer strscpy() instead of strcpy()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3fb167d7ceb7f22462743df93d9ed7f06eeaf6d0;p=thirdparty%2Fkernel%2Flinux.git

ALSA: spi: Use safer strscpy() instead of strcpy()

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

Only idiomatic code replacement, and no functional changes.
