Subject: [PATCH 03/11] iwlwifi: pcie: keep trans instead of trans_pcie in iwl_txq
Date: Fri, 29 May 2020 09:39:23 +0300	[thread overview]
Message-ID: <iwlwifi.20200529092401.1f826d34339e.I23182a59bfbe089a1f659742d6fee6f64d2ed08c@changeid> (raw)
In-Reply-To: <20200529063931.80551-1-luca@coelho.fi>

From: Mordechay Goodstein <mordechay.goodstein@intel.com>

We used both the trans and the trans_pcie structures in
iwl_txq, so we can keep the trans structure instead.  This
helps with the refactoring of txq code out of pcie.
