Subject: [PATCH v1 4/5] usb: dwc3: debugfs: Introduce DEFINE_STORE_ATTRIBUTE
Date: Thu, 22 Oct 2020 16:39:56 +0800 [thread overview]
Message-ID: <1603355997-32350-5-git-send-email-luojiaxing@huawei.com> (raw)
In-Reply-To: <1603355997-32350-1-git-send-email-luojiaxing@huawei.com>
Seq instroduce a new helper marco DEFINE_STORE_ATTRIBUTE for
Read-Write file, So we apply it at dwc3 debugfs to reduce some duplicate
code.
