Subject: [PATCH] OvmfPkg/GenericQemuLoadImageLib: Fix VS2019 UINT32 conversion error
Date: Sun, 29 Mar 2020 15:51:04 +0200	[thread overview]
Message-ID: <20200329135104.6560-1-ard.biesheuvel@linaro.org> (raw)

Building OVMF for X64 with secure boot enabled on VS2019 results in
the following error:

  d:\a\1\s\OvmfPkg\Library\GenericQemuLoadImageLib\GenericQemuLoadImageLib.c(154):
    error C2220: the following warning is treated as an error
  d:\a\1\s\OvmfPkg\Library\GenericQemuLoadImageLib\GenericQemuLoadImageLib.c(154):
    warning C4244: '=': conversion from 'UINTN' to 'UINT32', possible loss of data

Suppress the error by making the cast explicit.
