Subject: linux-next: build failure after merge of the hyperv-fixes tree

---

Hi all,

After merging the hyperv-fixes tree, today's linux-next build (x86_64
allmodconfig) failed like this:

arch/x86/hyperv/hv_init.c: In function 'hyperv_init':
arch/x86/hyperv/hv_init.c:447:29: error: unused variable 'dst' [-Werror=unused-variable]
447 | void *src, *dst;
| ^~~
cc1: all warnings being treated as errors

Caused by commit

f8162cff19f1 ("x86/hyperv: Remove BUG_ON() for kmap_local_page()")

I have used the hyperv-fixes tree from next-20221026 for today.

Cheers,

Thanks. I've fixed that.

I will also turn on CONFIG_WERROR in my build test.
