Subject: xenbus: avoid uninitialized variable warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=76ea3cb428c5dc4fd5a415a7651026caf198fb3d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

xenbus: avoid uninitialized variable warning

Older compilers don't recognize that "v" can't be used uninitialized;
other code using hvm_get_parameter() zeros the value too, so follow
suit here.
