Subject: [PATCH 14/19] firmware: turris-mox-rwtm: Rearrange probe calls
Date: Wed, 12 Jun 2024 15:54:38 +0200	[thread overview]
Message-ID: <20240612135443.30239-15-kabel@kernel.org> (raw)
In-Reply-To: <20240612135443.30239-1-kabel@kernel.org>

Rearrange probe calls:
- create the kobject (and corresponding sysfs files) only after the
  mailbox is created and board info is read
- initialize the completion before mailbox channel is requested
