Subject: [PATCH AUTOSEL 5.10 11/25] PCI: cadence: Use bitfield for *quirk_retrain_flag* instead of bool
Date: Sat, 11 Sep 2021 09:12:58 -0400	[thread overview]
Message-ID: <20210911131312.285225-11-sashal@kernel.org> (raw)
In-Reply-To: <20210911131312.285225-1-sashal@kernel.org>

From: Kishon Vijay Abraham I <kishon@ti.com>

[ Upstream commit f4455748b2126a9ba2bcc9cfb2fbcaa08de29bb2 ]

No functional change. As we are intending to add additional 1-bit
members in struct j721e_pcie_data/struct cdns_pcie_rc, use bitfields
instead of bool since it takes less space. As discussed in [1],
the preference is to use bitfileds instead of bool inside structures.
