A recent commit in Clang expanded the -Wstring-plus-int warning, showing
some odd behavior in this file.
drivers/isdn/hardware/avm/b1.c:426:30: warning: adding 'int' to a string does
not append to the string [-Wstring-plus-int]
cinfo->version[j] = "\0\0" + 1;
~~~~~~~^~~
drivers/isdn/hardware/avm/b1.c:426:30: note: use array indexing to silence this
warning
cinfo->version[j] = "\0\0" + 1;
^
& [ ]
1 warning generated.
This is equivalent to just "\0" so fix it to clean up the warning.
