Subject: [PATCH] media: tda8083: use time_after_eq() instead of jiffies judgment
Date: Thu, 10 Feb 2022 00:32:24 -0800 [thread overview]
Message-ID: <1644481944-15001-1-git-send-email-wangqing@vivo.com> (raw)
From: Wang Qing <wangqing@vivo.com>
It is better to use time_xxx() directly instead of jiffies judgment
for understanding.
