From 753ed9c95c37d058e50e7d42bbe296ee0bf6670d Mon Sep 17 00:00:00 2001 From: Joseph Salisbury Date: Fri, 16 Apr 2021 17:43:03 -0700 Subject: drivers: hv: Create a consistent pattern for checking Hyper-V hypercall status There is not a consistent pattern for checking Hyper-V hypercall status. Existing code uses a number of variants. The variants work, but a consistent pattern would improve the readability of the code, and be more conformant to what the Hyper-V TLFS says about hypercall status. Implemented new helper functions hv_result(), hv_result_success(), and hv_repcomp(). Changed the places where hv_do_hypercall() and related variants are used to use the helper functions.
