Subject: [PATCH V6 3/6] MdeModulePkg/UefiHiiLib: Validate question with bit fields
Date: Wed, 20 Sep 2017 21:09:51 +0800	[thread overview]
Message-ID: <1505912994-433548-4-git-send-email-dandan.bi@intel.com> (raw)
In-Reply-To: <1505912994-433548-1-git-send-email-dandan.bi@intel.com>

V6:Update EDKII extenstion MACRO name with EDKII prefix
which are missing in V5.

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=545

In UefiHiiLib, there are codes to validate the current setting of
questions, now update the logic to handle question with bit storage.
