Subject: [PATCH v2 2/4] scsi: ufs: Remove redundant null checking of devfreq instance
Date: Wed, 16 Dec 2020 21:16:37 +0800 [thread overview]
Message-ID: <20201216131639.4128-3-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20201216131639.4128-1-stanley.chu@mediatek.com>
hba->devfreq is zero-initialized thus it is not required
to check its existence in ufshcd_add_lus() function which
is invoked during initialization only.
