Subject: media: dibx000_common: use strlcpy() instead of strncpy()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b312598dd48ddf22a0d144ca08b898da605a9f1f;p=linux.git

media: dibx000_common: use strlcpy() instead of strncpy()

gcc-8 reports

drivers/media/dvb-frontends/dibx000_common.c: In function
'i2c_adapter_init':
./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified
bound 48 equals destination size [-Wstringop-truncation]

We need to use strlcpy() to make sure the dest string is
nul-terminated.
