Introduced by https://github.com/ClangBuiltLinux/clang/commit/a11ecd118716ebfbbcf77a48fffe7fa7bddad738. This diff should fix it properly (disassembly shows no difference). Just need to draft up the commit message and send it along (I'm probably going to wait until after -rc1 so that nothing gets lost plus I want to ping old patches).

Thinking more about this, I think just = ""; is better since the empty string literal is still NULL terminated.

This is equivalent to just "\0" so fix it to clean up the warning.

This is equivalent to just "\0". Nick pointed out that it is smarter to
use "" instead of "\0" because "" is used elsewhere in the kernel and
can be deduplicated at the linking stage.

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]

This is equivalent to just "\0". Nick pointed out that it is smarter to
use "" instead of "\0" because "" is used elsewhere in the kernel and
can be deduplicated at the linking stage.

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;

                                    &      [  ]
1 warning generated.

This is equivalent to just "\0". Nick pointed out that it is smarter to
use "" instead of "\0" because "" is used elsewhere in the kernel and
can be deduplicated at the linking stage.
