Subject: [PATCH edk2-platforms v2 2/3] IpmiFeaturePkg: remove buffer temporary buffer from BMC instance structure
Date: Thu, 9 Mar 2023 02:18:44 +0300 [thread overview]
Message-ID: <20230308231845.10895-3-mike.maslenkin@gmail.com> (raw)
In-Reply-To: <20230308231845.10895-1-mike.maslenkin@gmail.com>
There is no point to have temporary buffer in BMC instance data
used only for synchronous IPMI command as a transfer buffer.
Using local variables make things much simpler.
