Subject: [PATCH v1 1/8] firmware_loader: Clear data and size in fw_free_paged_buf
Date: Tue, 8 Mar 2022 13:49:25 -0800 [thread overview]
Message-ID: <20220308214932.24477-2-russell.h.weight@intel.com> (raw)
In-Reply-To: <20220308214932.24477-1-russell.h.weight@intel.com>
The fw_free_paged_buf() function resets the paged buffer information in
the fw_priv data structure. Additionally, clear the data and size members
of fw_priv in order to facilitate the reuse of fw_priv. This is being
done in preparation for enabling userspace to initiate multiple firmware
uploads using this sysfs interface.
