Subject: [Linux-kernel-mentees] [PATCH v2 2/8] IB/hfi1: Convert PCIBIOS_* errors to generic -E* errors
Date: Mon, 15 Jun 2020 09:32:19 +0200 [thread overview]
Message-ID: <20200615073225.24061-3-refactormyself@gmail.com> (raw)
In-Reply-To: <20200615073225.24061-1-refactormyself@gmail.com>
From: Bolarinwa Olayemi Saheed <refactormyself@gmail.com>
pcie_speeds() returns PCIBIOS_ error codes from PCIe capability accessors.
PCIBIOS_ error codes have positive values. Passing on these values is
inconsistent with functions which return only a negative value on failure.
Before passing on the return value of PCIe capability accessors, call
pcibios_err_to_errno() to convert any positive PCIBIOS_ error codes to
negative generic error values.
