Subject: [PATCH -next v4 1/2] platform-msi: Save the msg context to desc in platform_msi_write_msg()
Date: Mon, 30 Aug 2021 15:38:57 +0800 [thread overview]
Message-ID: <20210830073858.47084-1-cuibixuan@huawei.com> (raw)
Save the msg context to desc when when the msi interrupt is requested.
The drivers can use it in special scenarios(such as resume).
