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

[broonie]

Hi all,

After merging the hyperv tree, today's linux-next build (x86 allmodconfig)
failed like this:

/tmp/next/build/drivers/hv/connection.c: In function 'vmbus_connect':
/tmp/next/build/drivers/hv/connection.c:228:53: error: implicit
declaration of function 'hv_alloc_hyperv_page'; did you mean 'hv_free_hyperv_page'? [-Werror=implicit-function-declaration]

Caused by commit

  4dbdcfe1c5db80edca ("Drivers: hv: move panic report code from vmbus to hv early init code")

I will use the hyperv tree from yesterday instead.

This has been fixed by removing the problematic commit.

Thanks,

Adding more Hyper-V CCs, sorry the capitialisation in MAINTAINERS
confused my search.
