Subject: [PATCH RFC v2 5/7] ipmi: ls2k: Relax the dependency to its mfd driver
Date: Wed, 08 Jul 2026 05:16:29 +0800 [thread overview]
Message-ID: <20260708-ls2kbmc-mod-v2-5-2afdd1741766@gmail.com> (raw)
In-Reply-To: <20260708-ls2kbmc-mod-v2-0-2afdd1741766@gmail.com>
From: Miao Wang <shankerwangmiao@gmail.com>
There is no strong dependency between the IPMI driver and its mfd
driver. Although the IPMI driver will not work without the mfd driver,
it is not a hard dependency. The IPMI driver can actually be compiled
without the mfd driver, and it will just fail to probe. When the mfd
driver is loaded, the IPMI driver will probe successfully. Therefore,
the dependency of the IPMI driver on its mfd driver should be relaxed
to "imply" from "select". This will allow the mfd driver to be compiled
as a module and the IPMI driver to be compiled as a part of the ipmi_si
module.
Fixes: d46651d4e3c0 ("ipmi: Add Loongson-2K BMC support")
