Subject: tools/liblockdep: Correct macro for WARN
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=62b989de598c486df65a14dfd9bb4a9953c75568;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

tools/liblockdep: Correct macro for WARN

As Peter Zijlstra pointed out, the varargs for WARN() are
optional, so we need to correctly handle the case where they
don't exist.

This would cause a compilation error.
